Limit number of questions in survey - by: Breut

Hi all,

I'm using 2.00+ build 130708

I have 6 groups with 40+ questions in each group.
I would like to limit the number of questions shown from each group to the person taking the survey, e.g. show 10 random questions from group 1, 15 random questions from group 2 etc.

Please advise on how to proceed.

Thanks in advance,
Thomas
