_parent, _root ? help with targeting

Hello. I need some help with targeting a MC inside a MC.
I got the nested mc buttons to work but can’t seem to get the parent MC to work.
Any help would be great. Thanks also here is the fla.

ActionScript Code:
[FONT=Courier New][LEFT][COLOR=#808080]*/*--------------Main Header (Parent)---------------------*/*[/COLOR]

[COLOR=#0000FF]_parent[/COLOR].[COLOR=#000080]Header_mc[/COLOR].[COLOR=#0000FF]onRollOver[/COLOR] = [COLOR=#000000]function[/COLOR]COLOR=#000000[/COLOR] [COLOR=#000000]{[/COLOR]
[COLOR=#0000FF]_parent[/COLOR].[COLOR=#000080]Header_mc[/COLOR].[COLOR=#0000FF]gotoAndPlay[/COLOR]COLOR=#000000[/COLOR];
[COLOR=#0000FF]updateAfterEvent[/COLOR]COLOR=#000000[/COLOR];
