I’m looking for a way to pick out a unique item from a list. Simply put, when an item is only once on a list, I want to see it as an output, if there’s several of an item I want none of them in the output. Thanks in advance!

So I actually found the SetDifference node and it immediately solved the problem. Thanks nonetheless :wink:
