Hi there. I’m having trouble creating a nested IF formula with a date parameter.
I use airtable to calculate invoice totals for my business, and we have been offering a 10% discount on orders of 4 or more items. I use a field with this function:
IF(Quantity1+Quantity2+Quantity3+Quantity4+Quantity5 > 3, “------>”, “NO”)
and a BILLING TOTAL formula field outputs different numbers based on the response.
The problem I’m having now is that we’ve increased the threshold to 6 items before we offer the discount. I would like to create a nested IF formula that can take into account the date a deal is closed. I don’t want to change the formula to > 5, because then it will calculate our past deals inaccurately.
How can I add a condition that will apply the discount if > 3 only if {Date closed} is before 6/24/18, and > 5 if {Date closed} is either blank or after 6/24/18?
I know this is super specific to my database, but I hope someone can help me! Thanks in advance!
