The problem is here "Can't find variable: VAR_RANDOM_LIST_VIDEO".
Make sure the value of the variable is correct.
You can check this in the variable inspector.

Disable this option to take other rows from the resource in one thread.

notreuse only works for resources, it doesn't work for variables.
I've attached a sample project and a video.

@m4zuper My problem is that I have several paths, and depending on the parameters it has to choose different paths.
I always have a fixed part which could be C:\Users\image, and some variable folders which could be like…
C:\Users\image\dog\red
C:\Users\image\dog\black
C:\Users\image\cat\red
C:\Users\image\cat\black
I implemented it like this but it's failing. Do you have any suggestions for alternative approaches to accomplish this?
{{fixedpath|notreuse}}/[[cat]]/[[black]]
{{fixedpath|notreuse}}/[[cat]]/[[red]]
@m4zuper creating a resource for each folder is impossible — it would mean creating too many resources. I’ve thought about it. Can you explain to me how creating variables without resources works? Did you see the previous example where I created SET VARIABLE fixedpath/[[PATH1]]/[[PATH2]] and inserted this variable in open fail result? Even that didn’t work. Could there be alternatives?
