I want to make make a questionnaire with modular access. All questions are non mandatory and there is a Group structure.
User has to choose one or more Groups he /she wants to use. The rest stays unanswered
Choosing all Groups ( Serial approach) can als be a choice.
I hope I could use index for that but so far it can only back jump but not directly forward from start.
This also does not work ( forward) after answering a first q at start up.
I use newest version of LS

Set "Show question index / allow jumping" to "Full", this should allow moving forward.

Tried that Tony but alas not the desired effect

Err...could you give us some hints as to what "not the desired effect " means? Does that not allow you to skip forward in the survey?

"User has to choose one or more Groups he /she wants to use"
Maybe that could be done via a question, and then a scenario for the next group to show ?

Yes it does not move forwards ( not the desired effect(
