Collapsing Menu...Kinda Works

I tried to make a collapsing menu tonight. I got it to work fine, but when I started making changes, problems came up. When the Tweens are set to Strong (which they are in the attached file), everything works. When I change Strong to Elastic, though, I get some strange problems. Just Find and Replace Strong with Elastic to see what I mean. Could anybody tell me what I’m doing wrong?
