Kamy, you rule!
Snippet works just like I wanted it to. The only thing that I had to tweak was the quotation marks within
include($id[$randval]);
include(' $id[$randval]' );
I took them out and ta-dah! I have a tendency of putting extra quotes myself...
This solution is a lot simpler then some of the alternatives I was considering.
I hear you about the money!
