String Join To Element.SetParameterByName Not Working

[MickySteve]

I am trying to combine separate strings to create an unique string.
Is anyone able to help.

What do you want it to look like? Can you provide an example output?

I think you just need to flatten your input. You have a nested list that’s throwing off the lacing of the SetParameter node.

I have “Flattened” it and it works.
