Hello,
I have an interesting logical case, but can't find a solution.
There is one filter question (let it be B55). It's a matrix with 12 companies in the rows.
And there are additional 12 questions B56a, B56b, B56c etc. up to B56l (12 questions for each company). Each of these 12 questions can be asked only if in previous filter matrix B55 there was code 3 or 4 for the company (which means 'the person knows the company').
But only random 4 questions among these B56a...B56l can be shown.
If the person knows 12 companies - only random 4 must be shown.
If the person knows 4 companies - only these 4 are shown.
If the person knows 3 or less companies - only these 3 or less are shown.
I really need the advice.

Hi, synthoscope,
well, if the respondent only knows 4 or less companies it's just relevance.

To find your 4 out of "more than four" known companies you will find a starting point in the manual:
www.limesurvey.org/manual/Expression_Man...e_Question_Per_Group
and
www.limesurvey.org/manual/Expression_Man..._of_the_questions.29

Sorry, not to be of more help.

Kind regards

It seems to me that you can achieve the "If the person knows 12 companies - only random 4 must be shown" part by randomizing the question order and, for each question, have a relevance statement that requires the sum of the relevance status for all other questions to be less than 4. Search the forums for "relevanceStatus".

So, for example, the relevance statement for B56a would be something like this;
