Preloader inside empty movie clip.. not showing up?

Loading movie clips with:

on (Release) {
container.loadMovie(“http://www.atptennis.atponline.net/en/aboutatp/flash/organization.swf”);
}

The SWF file contains standard kirupa preloader:

bytes_loaded = Math.round(_root.getBytesLoaded());
bytes_total = Math.round(_root.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
_root.loadBar._width = getPercent100;
_root.loadText = Math.round(getPercent
100)+"%";
if (bytes_loaded == bytes_total) {
_root.gotoAndPlay(3);
}

Nothing shows when I load it in the empty movie clip called container. If I test the movie inside flash, it works perfectly. I am guessing it has something to do with “_root”? Any help would be great.
