Hello dear community,

I'd like to do the following task with limesurvey:

I have different categories with three or more members. Now I want the user to choose place 1, 2 and 3 in each category. Each place can only be chosen one time in each category.
p.ex.
Category 1 has members cat, dog, zebra and snake.
Now you can choose place 1 for the cat, 2 for the dog and 3 for the snake. But you get an error if you choose also place 2 for the zebra.

How can I get this logic into limesurvey?

Thanks in advance!

Please refer to the manual. Question type - Ranking - manual.limesurvey.org/Question_type_-_Ranking

Thank you very much. That was very helpful.

But inn the end we decided to use the unique(self) option on the matrix question.
