So I imported your LSS file.
Found this in one of the first questions: "did not geta a test", might want to change the typo.
Now I tested the survey with being 18 and I got the last page. Shouldn't the relevance equation prevent me from getting the last question? Oh, I think the relevance equation is wrong.
Code:
((Qage.NAOK > 13) or Qage.NAOK < 17)
I mean, if you use OR here, any age will get this question, because everyone is either above 13 or below 17. I assume you are looking for people older than 13 and younger than 17, right (14-16 year olds).
And then the brackets are also odd, there are at least some brackets missing or some too much. Will test some more.
