Hello,

I have a survey with a numeric question (Q13). Later I have a filter : the number of question depends on Q13.

Q13 / With how many person do you interact ?

filter[!is_empty(Q13) && Q13.NAOK > 0] -> Q14_1 : Person 1, mail, telephone, ...
filter[!is_empty(Q13) && Q13.NAOK > 1] -> Q14_2 : Person 2, mail, telephone, ...
filter[!is_empty(Q13) && Q13.NAOK > 2] -> Q14_3 : Person 3, mail, telephone, ...
...

But when respondants push finish later, Questions on persons details (Q14) disappear. LimeSurvey seems to ignore value in Q13.

Can you help me ?

Sincerely,

Can you attach a small test survey containing only those questions?

Here it is.

Thanks.

Well, I see at least 3 logic errors in that file. You have question validation equations like ! is_empty(Q14_1.NAOK) and ! is_empty(Q14_2.NAOK) and ! is_empty(Q14_3.NAOK) where there are only two sub-questions in that question.

Review the logic file, fix all errors and retest.
