Movie clip to low opacity when external movie is loaded

[aradada]

Hi all,

I have a movie clip with a button that loads an external flash movie when clicked. Once the external movie is loaded I would like the movie clip (that will remain as a background) to low its opacity. How can I do that ??? I'm using AS2 and the way that I'm loading the external movie is:

on (release) {
    loadMovieNum("new.swf", 1);
}

Thanks a lot in advance!

on (release) {
var loader = new MovieClipLoader();
loader.onLoadInit = function(){
    pathtotheclip._alpha = 50; // or whatever, 0 is fully transparent, 100 is fully opaque
};
loader.loadClip("new.swf",_root.createEmptyMovieClip(1,1));
 
    }

When publishing I get a "Type mismatch" error in

loader.loadClip("new.swf",_root.createEmptyMovieClip(1,1));

what's wrong??
Thanks!

Now I'm trying the following for a button in the main fla:

on (release) {
    loadMovie("movieloaded.swf", 1);

_root.myclip._alpha=20;

}

And then in a button in movieloaded.swf in order to unload the movie and restore the opacity:

on(release)
   {
      unloadMovieNum(1);
	 _root.myclip._alpha=100;
	
   }

The movie is loading great and the opacity in myclip is going to 20%.
When hitting the button in movieloaded, the movie unloads but the opacity of myclip is not restored to 100% it stays in a 20%.

What can I do? I need myclip back to its 100% opacity after the movie is unloaded.

Thanks once again!

Just in case somebody needs it:

on(release){
unloadMovieNum(1);
_level0.myclip._alpha=100;
}
