No such property: clan3 for class: Script2 Possible solutions: class

Hello everyone. I’m new here and I have a problem.

I’m trying to make a collection for multi instance subProcess.
First I select some values and on the end of the task set them to the proces.

set
my script.
script
After i try completing task previous to the script i get this error.

(limit to only two links :frowning: )

I have no idea what I’m doing wrong.
It was working for some time but now I always get that error, even if i change the name or location from which i set that “clan3”.

Thank you for your help in advance.
