Sliding objects

Hi!

I am trying to to achieve the effects at this site I saw (http://www.dfgw.com/flash.html), but I need someones help to complete it. In the files attached you can see three rectangular shapes sliding onto the stage. Hit the First one (one on the far left) and see what happens…When it is fully expanded to a bigger “panel” hit it again and see what happens. Yes, It becomes small again, but this is partially what i wanna achieve! How would I make it become smaller, and then slide back to ORIGINAL position (on the far left). there is something small I am missing, would appreciate some help! thanks mates!
