I am sure I have read something about this before either in the manual or in a forum somewhere but I can'y find it. What I want to do is ask a series of questions to a number of people. The number of times I want to ask the series of questions is determined by a question that says" how many of you are there". If for example the answer is 4 then I wish to ask the same questions 4 times.
So person 1 would answer questions 1-10
then person 2 would answer the same 1-10 questions and so on and so forth.
At the moment I have set up the same questions 6 times over so the maximum number of times I can ask them is 6 and obviously the "how many are you" question although not limited to 6 will only ask the maximum of 6 sets of questions.
I need it to be much more dynamic for example for between 1 and 30 people, and I don't really want to create 30 separate sets of the same questions.

There is no looping feature in Limesurvey yet. So your current approach is basically the only way to be able to do that:
- One question for the number
- then hiding/showing via relevance equation the respective number of question groups.

Sorry, but I currently see no way around this within Limesurvey.
