How to code
I made a questionnaire in xlsform and I have trouble coding well. My problem is this: there is a question to ask. If I answer “Yes”, four more questions come up. But in these four questions, at least one question must be greater than 0.
If you want I can send you the questionnaire in xlsform.
Thank you in advance

Welcome back to the community, @allmylife017! Sorry, I could not understand this very well:

Could you kindly explain it again?
