List/Extraction help!

Hooray for my first post in the forum!

Despite taking awesome sessions at the conference on this very topic from both Kevin and Anna, I'm currently finding myself stumped.  Using various criteria in both lists and extractions I keep coming up with a bunch of 0s.

Here's the deal: I'm trying to pull a list of all subscribers who subscribed into all of the 7 plays in our season.  What I've been doing is, in extractions, using Pkg code as my criteria and selecting one of our 7-play package codes, then in the "or" field selecting the rest of them...and I keep getting 0. 

Thoughts, dear reader?  I will also eventually need to pull lists of subscribers who are seeing certain shows but not other shows.

Thanks!
