I have created a survey with checkboxes questions. I set these options in most questions:
Mandatory: no
Max number of answers: 1
Min number of answers: 1
If my user checks more than 1 answers on the same question he gets this message: this is a requested field (or similar, I have the italian version) and not that he cannot check more than 1 answer. If he unchecks all and repeat the procedure, he gets the right message. Why? Could you tell me how to fix this? I can give you an account in order to take a look. Thanks.
