Tweeking kirupa's load script

from kirupa’ site :

bytes_loaded = Math.round(this.getBytesLoaded());
bytes_total = Math.round(this.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
this.loadBar._width = getPercent100;
this.ltp = Math.round(getPercent
100)+"%";
if (bytes_loaded == bytes_total) {
this.gotoAndPlay(3);
}

i don’t need it to load the entire movie, just say 32kb of it…
any way i can get it to do that?

i tried
bytes_total = Math.round(this.getBytesTotal()/2);
but that doesn’t work =\

ok i got this


bytes_loaded = Math.round(this.getBytesLoaded());
bytes_total = Math.round(this.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
this.loadBar._width = getPercent*100;
//this.ltp = Math.round(getPercent*100)+"%";
check_sum = (bytes_total/2);
if (bytes_loaded > check_sum) {
	this.gotoAndPlay(3);
}
