Problem with loading

I have little problem with my site, i have a MovieClipLoader class and i’am loading external movies to my index.swf. Ewerything is fine but when i load for example a products.swf with couple of links to index.swf i cant get them to work. For these buttons i have code

this.ubrania.onRelease = function(){
		 _level0.container1.loadClip("ubrania.swf", container);

That should be working but its not.
please help me with that one.
