[RESOLVED] loading movie from target in another file

I need to know how to loadmovie into a target that is located in another file that is loaded onto the stage. Any suggestions? AS2

Solved.

Something like this would work
on (release) {
loadMovie("side.swf", _root.center_mc.map_content);
}

But if anyone does know how to get into a particular FILE and not just root would be helpful as well
