Going back to root in an externally loaded .swf

Hey everyone,

So i have a site, with externally loaded .swf’s in empty movie clips. In those .swf’s, if i point a button back to the _root, instead of staying in that movie, it goes back to the original movie that they’re loaded in, rahter than the root of the external .swf. Can someone please tell me how to distinguish in code, where to go?

Thanks
