Stuck on Listview checkbox

[Jewtus]

I found a few scripts that I'm going to leverage:

and I started tweaking it and I've gotten to a point that I'm stuck. I can get the root level see if it is checked or not, but it doesn't seem to dive any further down. What I really want is to grab the entire path from the check boxes.

Any idea why its not seeing that the child elements are checked off? Also, any suggestions on getting the full path for the checked off child elements?
