AS2 - communicating from a loaded Movie back to the container movie

I am using “loadMovie” to load external swfs into a movie clip holder. I want the “close” button on the loaded movie to unload the swf and also communicate back to the main movie but I can’t seem to get it to work. I have tried _parent, _root, and variations of both but to no avail.

Nevermind, it seems _parent._parent is working.
