Based on replays in this tread:
forums.limesurvey.org/forum/can-i-do-thi...array-answers#192662
I had similar situation in a my survey so I set as suggested:
1 an hidden radiobutton choice question and
2 a Equation hidden question
3 the radiobutton question filtered by the first hidden question
and this solve perfectly my needs (this 3th question is mandatory).
The problem now is about this beavior: after i pass over the three Questions above and supposing the user turn back in the survey and change the choice that is the filter criteria when back to the question 3 can totally ignore of make a choice at the answer and can go ahead bypass the mandatory questions!
Of course I think this appen because the first choice is recorded in the survey memory so the survey "think" the answer was done.
Hope to be clear exppsing my issue, have you some suggestion to resolve this particular behavior??
Thanks in advance
