Horizontal Drop Down Menu Help

I’m trying to put together a horizontal drop down menu using the Tween and Easing Classes. I’ve got the thing set up and basically working (I use this term loosely). I’m just having problems with getting it to act like a menu. I’ve attached the .fla, can anyone give me a hint on how to get it working?

** If you take a look at the .fla the only button I’ve done so far is the ‘Services’ one, if I can get that one working I’ll get the others goin.
