Embedded movieclip actions not working (dropdown type menu)

programming flash
1

I have a dropdown style menu that has some movieclip buttons inside it and when I click on the movieclips the actions aren’t working.

Here is the file I’m working on. Rollover the head on the border and you’ll see what I mean.

I tried searching but couldn’t find any threads that answered my question about why the MC doesn’t work when its embedded inside another MC.

Here is the code (first frame of root timeline) that is used for the movieclip button:

_root.odinHead_mc.videoGalleryButton_mc.onPress = function() {
	_root.videoGallery_mc._visible = true;
};

Any help is greatly appreciated…I’m sure its something simple I just can’t seem to figure it out.
