I’ve successfully added transitions to my site, now i want to add pre-loaders to it.  
I copied this code:

> midframe=39;  
> bytes\_loaded = Math.round(this.getBytesLoaded());  
> bytes\_total = Math.round(this.getBytesTotal());  
> getPercent = bytes\_loaded/bytes\_total;  
> this.loadBar.\_width = getPercent_100;  
> this.loadText = Math.round(getPercent_100)+“%”;  
> if (bytes\_loaded == bytes\_total) {

this.gotoAndPlay(3);

}

when the file loads I get this message : “A script in this movie is causing it to run slowly…” What am I doing wrong?
