You have to create "scenario"..
There is a case (numerical input) available for this.
scenario #1 .......
OR
scenario #2 .......
OR
scenario #3 .......
BTW you can use the relevance field + a formatted expression,
like (depending on your question type):
((Q1.NAOK == "1")) or ((Q1.NAOK == "2")) or ((Q4.NAOK == "2") and (Q6.NAOK == "1"))
I added anoter scenario and clicked "Add condition" but I did'nt change the scenario name to "02". That was my mistake. When I did it, the problem has been solved as you described. Thanks a lot!
