Help Needed for Masking Loadmovie. URGENT!

I'm trying to load an external swf via LOADMOVIE using this

{
_root.createEmptyMovieClip("container",1);
loadMovie("MovieLink", "container");
container._x = 555.95 ;
container._y = 21.00 ;
}


Now its loading the parts outside canvas too in the loaded movie so that it looks quite messy. I was reading about masking, but I'm too much of a noob to understand that. How exactly do you mask the outside of the loaded movie via actionscript>?

Hoping for a fast reply, its kind of urgent.

Thanks in advance

Don't dynamically create the container. Instead make an empty movieclip on your timeline (make sure to give it an instance name). Then on the layer above create a shape for your mask. Remember the filled in parts will allow your content to show through.

Now load the movie into your empty clip instead of the one you created with actionscript.
