Hello.
I'm trying to get a variable called "responseId" from Forms and perform a calculation on it, but I get an error.
I think the syntax is correct, but is there any reason for the error? An error occurs when I insert subtraction in the formula in the figure.
***
my Flow was fixed well.
However I still don't know the reason why for the problem.
If someone knows about this, please give me information.
Thank you very much for your all support.
