Is it as simple as missing a colon:

Ugghh! That was it! Couldn't see the acorn for the forest. :)

And I'm confused about WB1 and WB2. In your text, you say you want to pick up
the list from WB2, but in the code you use WB1.

No. That was the problem. It was picking up data from WB2, and I
wanted it from WB1.

Thanks!
