I think that the issue lies not with the element input, nor the parameter name input, but from the list management. Change your lacing to “cross product” instead of shortest for the Element.GetParameterValueByName node, and maintain the rest of the graph as it was originally done and you should get the intended results.

I’ll see if I can get it to work with these instructions and then I’ll update the thread.


Thanks! It was as simple as this:
