Saying it "don't work" isn't very helpful. What doesn't work? How are you running it? I can run multiple or consecutive instances of the script and it works fine every time. You need to provide more details.

Well don't do anything the second time you use the function in the same run, ex: i need to set collapsible 38 groups and only set the state to one of the groups, or simply change the name to the 2 groups like in the example in this bug.

See the new example with MsgBox.
