Auto-number unique to items in table

Welcome to the community, @Jay_Stuart! :grinning_face_with_big_eyes: If I understand you correctly, you’re trying to add an alpha prefix to the autonumber to create a unique ID, so that things in the [Children's] table would be marked C1, C2, C3, etc. If that’s correct, this can be done with two fields: the autonumber field—which can remain hidden after setup—and a formula field to tack the letter of your choice onto the front. If the autonumber field is named {Autonumber}, the formula in the {ID} field would be:

"C" & Autonumber

Is that what you want?

Thanks Justin
I redid the gris so the auto number was hidden, However in the formula I used;
CONCATENATE(‘A’, {Autonumber})
It works like I wanted it to work.
Now I have an issue I’m not sure what to do.
A form will be used to enter the items into the database and when the form is submitted the item will be given a number via Autonumber. I need to be able to have the person entering the item to be given the generated number so it can be placed on the item itself.
How do I do that without having the person go to the grid?

Ideas?

Airtable forms don’t offer any kind of post-submission feedback mechanism based on the newly-created record, so you’ll likely need to enlist the help of third-party tools. I’ve got one possible idea in mind that might work using Jotform, but part of its viability depends on a specific aspect of your use case: will you have multiple users creating new records at the same time using the same form?

Justin, I would like learn about what solution can be to the same thing. I want a recordID that refers to the table, ie Mytable(n), where n is the autonumber of that record. I have been been able to create it using concatenation but how do I communicate this to the user. I want to use it as their ID, subsequently for their use of the database.
