I would like to be able to use different groups of questions depending on a user and their membership to a different group. for example person a is a member of group X. There fore they need to answers questions from question pool 1 only. Person 2 who is a member of group Z needs to answer questions from Pool 1 and pool 2. How do I this?
although not exactly what you are asking here, it shows the techniques on how to make specific fields on a form ‘mandatory’ based on conditions, and the 3rd element where a field is ‘mandatory’ based on the content of a form field could be the one you need, replacing the ‘is mandatory’ with field state is normal (ie visible) or hidden for your questions
