Randomized 1/4 LOOP

OS (e.g. Win10): WIN11
PsychoPy version (e.g. 1.84.x): 2022.2.3
What are you trying to achieve?: I’m trying to do a random selection of 1 loop out of 4. I mean, each time only one loop out of the four will appear. At the moment I manage to have the order of the loops be random, but all four loops appear and not just one of them

What did you try to make it work?:

I tried to do outerloop that attach an Excel file like in the above picture. But still all the inner loops appear and not just one of them.

thanks for any help

If you add the code model.finished = True to a code component within the loop then it will only present the first iteration.
