David, I can't thank you enough for your quick reply! Very patient & methodical approach. Very easy to understand video!
I can follow on a new plan & will tinker a bit with that, following your video, and then try to fix my plan.
The software steps can be a bit non-intuitive (it appears as if it is ignoring the top floor when indeed it is not checked).
Thanks again & I'll give an update after i've tried on my own a few times, following your tips. Thanks!!!!!
