Hi, If the list is empty (True) I’m trying to pass another. If it isn’t (false) I want to pass that one. Not sure I understand if conditions correctly though. [image] Im sure im using it right testing this below [image]

Something like this might help. lstAll = [lst1,lst2]; List.Count(lst1) >= 1 ? lstAll[1] : lstAll[0]; Idea is to just combine both into one list and use list indexing as the changing value in your if statement, allowing you to pull the first or last value accordingly.

Completely correct but unfortunately the If node has its quirks:
