TOPIC: Compare numbers from fields

Compare numbers from fields 2 years 1 month ago #42623

Hello,
I would like to know if there is a way to compare numbers while entering a form or at least before sending it.

I explain myself, in the context of a reservation request we can define the number of people present, but also the number of t-shirts according to the sizes (XS, S, etc...), and the person who completes the form must put the desired number of t-shirts in each size (3 XS, 1 L, etc...)

But I would like to check that the total number of shirts indicated (the addition of the quantity of each size) does not exceed the number of participants.

For example, if I have 5 participants I can only have 5 shirts in total for all sizes.

I hope my research is clear enough

Thank you in advance for your help
