Elefront Bake Attributes

Hi, I’m new to the latest Elefront and used to using the legacy version of bake attributes. If would be useful to see a visual setup of how you bake layer and name attributes etc. Below is my current attempt, which is throwing up an error. Any help would be greatly appreciated!

I am assuming the error message is telling you that the trees need to match exactly - so it should be as simple as using Longest List or Cross Reference, etc. to create two matching trees for the “G” and “A” inputs.
