Hello fellas,

I am trying to use MovieClipLoader.onLoadProgress and I used code from some tutorial and can not [color=blue]_trace(percentage);_[/color] to work.

```auto
 this.createEmptyMovieClip("e_mc", 2);
var mcl:MovieClipLoader = new MovieClipLoader();
var mclListener:Object = new Object();
mcl.addListener(mclListener);
var bl =e_mc.getBytesLoaded();
var bt =e_mc.getBytesTotal();
mclListener.onLoadProgress = function(e_mc, bl, bt){
var percentage = Math.round(bl / bt * 100);
trace(percentage);
};
mclListener.onLoadComplete = function(e_mc)
{
// do what you want
trace("finished!");
};
mcl.loadClip("TITLE.swf", e_mc);

```

Do you know where is the problem?
