I want to make a preloader that begins my flash movie once it has 25% or 50% of the swf loaded. This is what I have on my first frame of my preloader right now:  
bytes\_loaded = Math.round(this.getBytesLoaded());  
bytes\_total = Math.round(this.getBytesTotal());  
getPercent = bytes\_loaded/bytes\_total;  
loadBar\_mc.\_height = getPercent_179;  
this.loadText = Math.round(getPercent_100);  
if (bytes\_loaded == bytes\_total) {  
this.gotoAndPlay(3);  
}

This works fine and dandy.

I’ve tried:  
bytes\_loaded = Math.round(this.getBytesLoaded());  
bytes\_total = Math.round(this.getBytesTotal()/2);  
getPercent = bytes\_loaded/bytes\_total;  
loadBar\_mc.\_height = getPercent_179;  
this.loadText = Math.round(getPercent_100);  
if (bytes\_loaded == bytes\_total) {  
this.gotoAndPlay(3);  
}

and I’m getting errors.

Can anyone help??
