Level Navigation

I have a movie structure like
_root(MainTimeLine) -> mov1 -> mov 2 -> mov3

Now this is in Scene 1
Now I want to jump to Scene 2 when mov3 is clicked. I tried
_root._parent._parent.gotoAndPlay(“Scene 2”)

But this is not working, any suggestions.

More explanation on this—

There’s a button on the main timeline(the topmost level).
I has got action (rollover) which attaches a movie(mov1) to the root, which contains movie(mov2). mov2 inturn contains another movie(mov3) on whose click the gotoAndPlay should occur.
