Oh god thank you.
I put the custom columns settings entries on separate lines. Works great now.
Also, composite columns seems like a good way to go. I'll give that a try.
And thanks for the note about the lack of edit notifications. I had a feeling that was the case, but I really didn't want to spam the thread. I see now that it may have been necessary. Imagine if you saw my post before the edits! D:
Thanks again for your help! You rock!
