Space Naming into Elements parameters

Hello folks,
Am trying to naming the MEP elements as per the space name,
when i try single categories its works fine, but when am trying combine multiple categories
SpaceNaming.dyn (27.3 KB)

it showing error,
can anyone help

What is the error message?


The error means the output of this node is not an actual element but just a string. Can you show the results drop down?



For single categories it works fine

@naturalnature what happens if you use List.Join instead of List.Create?

Try changing the Level on the _element input here. Also, you may need to play with Lacing like Longest.
