A path problem for the button. Help please

Hi,
I have button inside a MC (attached by linkage):
this is the path I get with trace(this) for the button:
[AS]
_level0.MC1.MC2.MC3
[/AS]
What I want is when button being released the movie goes to scene X at frame 1.
I have tried with
[AS]
_level0.gotoAndPlay(“X”,1)
[/AS]
it doesn’t work. When I have a test button on the _root, the scene shift works for this button on the _root. The problem is the path I think for that button which is inside the MCs.
Any help please?
