Reference via Relative, need help please

Hmmm I have somethin I want to reference relatively but it won’t work D:

Tree looks like this:
Scene 1 (Main Timeline) > scroller_subnav_mc (Movieclip) > content (Movieclip) - Button I’m puttin code on is in the content (MovieClip).

In Scene 1 there is a MC named container2 I’m trying to reference too… I have been doing this…

_root.container2
was working fine, but I’m going to load it externally so I would like the path relative.

_parent._parent.container2
I tried but it doesn’t work D:

But it won’t work?
I’m doin it this way because its going to be externally loaded and wuld rather have relative paths.
