Why won't my nested btn move its' parent?

Hey all,

I have a simple question, but for some reason I cannot get it to work…maybe it’s a Flash scope thing.

I have 2 child movieclips nested into one working parent movieclip, then the parent movieclip is animated. The nested working parent movieclip should move to the side once a child movieclip is clicked. Currently, the parent is unaffected by clicking on a child movieclip. What gives?

Below is a layout of the movieclip:
Button List Box
| |
v v
Subparent(groups btn and list box)
|
v
Parent(animated)

I need the parent to animate once the child **Button **is clicked.

Thanks.
