Formulas

Hi All, I am very new to airtable and trying to decide if this tool is right for our team. I think that it is, I am just having an issue trying to calculate the percentage. I have a count of subtasks as well as a count of the completed subtasks (linked record to another table,‘subtasks’). I wanted to use these two fields to calculate the percentage of completion. I added a new field and called it percentage complete and used the below formula: {Number of Completed Subtasks}/Number of subtasks and formatted as percentage. Since some items do not have any subtasks at all (0) I am getting the NaN error for percentage. How can I rectify this so that the NaN error, essentially 0/0 returns an actual percentage to help me with the bigger picture? I have added a screenshot for reference: any help is appreciated, thanks!

It’s 2020 halfway through. Are we getting trig functions in formula field? I need to have the ability to instantly calculating values when some fields are populated (no script block manual triggering).

Hi, I’m new here and trying to create a simple product catalog for a client, I’m looking at the template " Product Catalog" but I don’t know how to send an order form to the final client (where can I see how to create one), how the final client can chose the product, quantity, etc. I viewed most of the info and videos online but I didn’t find that yet…I already checked the product catalog page but still don’t know how to link the product catalog with an order form from the final client… please help! thanks

Hi there, I was wondering if someone could help me create a formula so that if I have a Text field, it can automatically add a “( )” around the first 2 or 3 digits? I know I could use the phone number field option but I rather not. EX: 1301234901 --> (130)1234901 OR (21)301234901 So far this I’ve gotten the following but they’re applied in separate fields. EX: “Field 1- Number”, Formula: LEFT({Number}, 3) As you’ll see by using this formula, it only isolates the 3 characters. Ex: “Field 1- Number”, Formula: IF(LEFT({text number}, 3),"(") This only gives me the ‘parenthesis’ in return. All help is appreciated :grinning:

I am not sure how to add in an “or” situation to this formula. Here is my formula: IF({Task Start Date},IF({Task Status}=‘Completed’,{Description}&" | “&‘COMPLETE’&” | “&DATETIME_FORMAT({Status Updated},‘MM/DD’),{Description}&” | “&DATETIME_FORMAT({Task Start Date},‘MM/DD’)),{Description}&” |") This only works if my Task Start Date is completed, but I need the Description to show regardless of the date column being filled. Does this need an if/or statement? Thanks!

Hi there, I am a relatively new Airtable user with a basic understanding of formulas which has held me in good stead until this week. I have a table linked to a form. It’s a form designed to use for a customer to hire various types of product for us. The form populates all the required information into a table where it shows all the relative information to us about what product they are hiring. The products are theatrical props and theatrical costumes. In the table, there are fields for “collection date” and “return date” for each above category and currently I have a field called “number of days hired” for each category that is reading those dates and working out the amount of days that product is hired by the current formula: DATETIME_DIFF({Date for costume return}, {Date for costume collection}, “days”) This field then multiples with the cost amount in a further field to tally the total cost. My issue is that when one of the date fields i

So I have a column titled “Days Since Update” which is the days since a certain date to today and then “Field 10” is based on an If Formula (if the status is completed it gives a 0). I now want a formula column which gives the smallest of these two values. I’ve tried Min formula however this ignores logical values (values in field 10). Does anyone have any suggestions? All I really want is that when the status is completed a value doesn’t come up in Days Since Update! Is there a way I can merge the Min and If formula together to achieve this? image|281x500

To create a more efficient process in pricing materials I’m working through different ideas and it’s just becoming messy. I’m trying to figure out if a formula would provide the best option or possibly a drop-down based on conditions. Example : I’d post a picture of my base, but it’s not quite finished, which is why I’m reaching out. If I need to purchase paint and paint supplies to bid materials needed correctly I’m trying to find the best option to fill in QTY TO ORDER gallon of paint is $30.00. Coverage area is 200 SF paintbrush is $2.00 needs replaced after 100 SF All materialS, coverage/price breakdown, is listed in a materials table. In the Bidding table I’d like to: COVERAGE AREA MATERIAL QTY TO ORDER PRICE Manual input SF, LF, tile count, etc. Manual input based on linked field

I have a category called frequency and it has four options. I want when i select one option another option automatically imputed in another category .

I was wondering if there is a way to do a percentile calculation in Airtable. Basically I’m trying to determine salary percentiles (in my case let’s say 75th percentile). So say I have a column of salaries in a “Positions” table with 25 rows (mine has way more, but for the sake of simplicity). I figured out that I can do the linked record trick to get all the values pulled into a single cell in another table, call it “Summary”. So i would use a lookup field to pull all 25 salaries from “Positions” into an array in the other table. I can then do a count of the number of values in that array. Then in theory I would multiply that count times my percentile (0.75 in my example), and round the result up to an integer, n. Then it’s a matter of finding that nth value in the array. BUT the array isn’t in order, so without being able to sort the array in ascending order, I can’t actually do the percentile. Anyone have any experience with this type of problem and a

Hi! I need a formula to calculate the average of the previous 4 weeks %. Screenshot attached. Does anyone know what I would need to put in for that? I’m assuming the July overall column needs to be a formula, right?

I want to count the number of attendees on course. I’ve uplodad a pic of the formula. Any ideas what I’ve done wrong?

I’m trying to create an inventory of our IT hardware, using computer names and the users associated with those names. I have access to the model number of the computers, but I want to be able to convert that model number into an easier identity that laymen would understand at a glance. Here’s an example: Name, Computer Name, Model #, Model Name Michael, PC01, 10HY002AUS, ThinkCentre M700 Tiny This last column is what I need to generate, based on the “Model #” - I know I can do this with a VLOOKUP in Excel, is it possible to do in AirTable?

How to create a new field from searching the value of two fields from the same table in another linked table. For example I want to get the serial number of a PC knowing its name and location (in the same table) but the information needed is in another extended table linked to the table where I want to put the result.

I am attempting to calculate a cost per validation in a table using a Formula of two rollup Fields but I want the results to show either the resolution of the problem {column A}/{column B} or “0” if NaN or the sum of Field 1 if Infinity. Examples of problems: if Field 1 rollup is $1800.00 Field 2 rollup is 0 I need the formula in Field 3 {column A}/{column B} to show $1800.00 not Infinity if Field 1 rollup is $0.00 Field 2 rollup is 0 I need the formula in Field 3 {column A}/{column B} to show $1800.00 not NaN if Field 1 rollup is $1800.00 Field 2 rollup is 2 I need the formula in Field 3 {column A}/{column B} to show $900 Getting the formula to give me the last result is easy enough - but I can’t seem to figure out how to use nested if formula to give me either 0 or Feild 1 amount. Is anyone else able to help me build this formula? Please and thank you so much if so!

I use a formula filterByFormula=Lower(E_Mail)=Lower("{user_email}". If there is a special Character of # or & or + in the e-mail address, for example debby+maier@gmail.com the formula does not find correspondig records in airtable. Special Characters like !$%’*-/=? within the E-Mail address are found. Can someone give me a workaround or solution. Thank you for your help

I am working on a database of the individuals in our feeding programme. In December we host an annual Christmas party for the kids between 5 and 16. How do I write a formula to identify these children? I have tried variations: IF({Current Age}>4 AND {Current Age}<17), ‘invite’) or IF( AND({Current Age}>4 {Current Age}<17), ‘invite’) and I just keep getting error messages. Clearly something is wrong with my format but I don’t know how to fix it. Please help :slightly_smiling_face:

Hi there, I was able to grab a formula from this amazing community to show status of due items, which is working great – but I need to add in one layer and my attempts so far have only produced errors. Not sure if it’s possible or what I’m doing wrong. The current formula: IF({Due Date}="",“Not Set”, IF(AND(DATETIME_DIFF({Due Date},TODAY(),‘hours’) >=12,DATETIME_DIFF({Due Date},TODAY(),‘hours’) <=48),“Due Soon”,IF(IS_BEFORE({Due Date},TODAY()),“Past Due :no_entry: ”, IF(IS_SAME({Due Date},TODAY()),"Due Today :eight_spoked_asterisk: ",“Upcoming”)))) What I need to add to the above is : If Due Date is before today AND “Status” column = Done :heavy_check_mark: , then value should show as “Completed” Appreciate any help!! This community is amazing, and I’ve learned so much from you!

How do I insert a blank in a concatenation formula?

Hi all! Thanks for taking the time to read this, I am migrating from Google Sheets and really need an inventive solution to this problem. I’d love to know your thoughts. My company run Zoom workshops and we are required to generate registers with time in/out. Zoom gives me a CSV file with this data, but it often enters the same client accross multiple rows. I then need to apply deductions for any period of time where the client was offline during the session. Time in Time out Deductions 1 ␣ 09:28 ␣ 09:37 ␣ 00:00 2 ␣ 09:34 ␣ 10:16 ␣ 00:00 3 ␣ 09:44 ␣ 10:16 ␣ 00:00 4 ␣ 10:18 ␣ 10:37 ␣ 00:02 5 ␣ 10:19 ␣ 10:37 ␣ 00:00 6 ␣ 10:38 ␣ 10:44 ␣ 00:01 7 ␣ 10:40 ␣ 10:44 ␣ 00:00 I can use a roll up to identify the MAX and MIN times, but cannot work out the deductions. To achieve this in sheets I did {Time out 2} - {Time in 1}. This had to be applied once the data was appropriately sorted using a macro. Clearl

I’m trying to calculate a formula using the if function but not sure where to start. My formula correctly calculates the wholesale cost of a case of 12 bottles of imported wine from the ex cellar price. However, still wines under 14.10% Alc are taxed at 25% of the value (ex cellar x 1.25), still wines 14.1% and higher are not taxed, and to make things even more exciting, sparkling wines are never taxed. I want to make one formula that incorporates whether the wine is taxed or not. can anyone help? in my formula: ex cellar = price of 1 bottle of wine in EUR, 1.15 = est exchange rate 1 EUR= USD, 12 = number of bottles in a case, 18 = cost of shipping in USD to import the wine, 0.6 = target 40% margin on final price. everything works fine, just not sure how to inco

Hi @all, I am trying to move everything that has the “finished” checkbox checked to another table. Is this possible? I am using integromat’s automation system. here is what I’ve tried:

I’m trying to figure this out and can’t for the life of me. Basically, this was a template in the AirTable Universe and when it’s a meal from leftovers I want it to say not just “Leftovers”, but which leftovers: ie “Leftovers (Beef Tacos)”. But I cannot for the life of me figure out how to do it. Here’s the formula that is currently in the table: I tried to do nesting IF statements and could not get it to work. I saw on a different post here that some people have conditional roll up fields, but I don’t seem to have that option (there’s no toggle on my roll up options to add conditions). Help is appreciated.

Hi All, I have a formula which finds a single instance of a string in a field but I would like it to find multiple instances of the string in the field, how should I change the formula? MID( {Field Name}, FIND( ‘beginning of string’, {Field Name} )+6, FIND( ‘end of string’, {Field Name}, FIND( ‘beginning of string’, {Field Name} ) )-(FIND( ‘beginning of string’, {Field Name} )+2) )
