Tell you what: It's 5pm here and I'm going home. In the office I have only xl 2003, but at home I have 2007. I'll open one of the versions above in 2007 and try to get to the bottom of it. If it works for me in 2007, I'll post it back. That should take care of the compatibility issues.

Hang in there. We'll get it done!

cheers
