Hi!
I would like to determinate the number of uploads depending on previously answered questions. Example: there are 3 Y/N questions Q1 to Q3.  Depending on the number of Y, a certain number of uploads should be necessary. So if Q1 == Y, Q2 == N, Q3 == Y. -> There must be 2 Uploads f.e.

Is this possible?

Best regards!

Try this in the "Maximum number of files" setting: count(Q1, Q2, Q3)

thank you! but, ... in my case it isn't that easy i think.

i ask people 1) whether they have invalidity or not (Y/N question) and 2) if they are from a third country I need the residence permit (folding box with answer "third country")
Also I always need a passport copy.
So i want to force that there are at least 1 or 2 or 3 uploads, depending on the answers to invalidity and nationality.

Maybe there is a solution using a thing like {countif(Q1 == "Y", ...)+1} ? i never worked with such expressions before...

sum(
intval(Q1.NAOK == "Y")
