Joining string lists. Drop the nulls

Lists-Logic

Probably an easy one for you guys.
I’m trying to join two lists and only keep the values that aren’t null or “”.

Using the A+B drops D. Why? Is there a better way?
Thanks again!

Thanks! List.SetUnion was the solution. So simple :smiley:

I got excited that it appeared to work, but it put the results out of order. Keep the list structure is vital.

Hi @Jack ,

I think in your first attempt with the Code Block “a+b” does drop the last item since it is (automatically) set to shortest lacing.
If you use the + node, not a code block, and set it to longest lacing it should work.
