Hi @hiti ,
What's the error message when submit your form?
You mentioned "recently I noticed", so do you mean this function work fine before and suddenly don't work?
I would suggest you check all columns mentioned in your formula, check if anyone edits one of these columns to a required column.
To narrow down your issue, you can also remove these column DataCards from your form one by one, remember each time to re-test Submit function.
If still cannot find the cause, for better understanding your issue, please provide your complete formula here(better with screenshots), so that we can test your formula on our sides.
Best regards,
Allen
