Loading external swf into mc

I have a flash movie containing several movie clips. In one of these i want to load an external swf (photo gallery).

Can someone help me with this?

I have searched through the forum but i can only find these answers which is NOT working:

1.var loaderMcl:MovieClipLoader = new MovieClipLoader();
loaderMcl.loadClip(“nameofswf.swf”, container_mc)

2.container_mc.loadMovie(“nameofswf.swf”);
