Hi there, I have no clue why the code suddenly generates an error and the randomization doesn`t work anymore.

I attached a screenshot. It worked perfectly in the same questionnaire then suddenly it turned into an error. I use LS Version 2.65

I also use a second code. Maybe this causes the error. However, I used the code (both) in other surveys and it always worked perfectly. And, as mentioned, the first test ran without any problems and then the error appeared.

I have really no clue, what went wrong. I checked the survey logic and everything seems fine.

Thanks a lot for your help!

Check survey logic file, sometimes error are shown even if it's OK.

Also preview the survey. I have had rare instances where a false error was indicated until I submitted at least one survey group.
