Hello Limesurvey community,

I am currently designing a survey that shall have the following structure:

1. Main Part 
2. Extras  

After completion of the main part I want to ask three out of the six extra question groups (called extra1-6) on a random basis. Randomization only works with questions but not question groups. Through research here in the forum I got familiar with the concept of asking a hidden equation question and then using a dependency to assign question groups randomly to users. My problem is that I don't see a way to repeat this step several times while making sure that the user does not see one of the extra question groups twice or even three times. Also for my survey it is important that the extra questions groups are assigned randomly. So simplifying things by assigning the users to fixed sequences of questions groups (draw random number, if random number = 1 assign extra 1, extra 2 extra 3, if random number = 2...) doesn't seem to be an option. 

As I write this late in the evening after a long day of work, I really hope it is clear what I mean. I consider myself a beginner Limesurvey user so any help and suggestions are welcome. Sincerly

Hi,
as you noticed the approach with random numbers is wrong.
You may instead:
1. Sum the "relevaceStatus" of one question of each group and terminate if it is equal 3.

2. Create three unique random numbers by javascript

Not more as you not only ignored the questions at the beginning but removed them.

Send a lss export of a sample survey with these relevant questions.
