It's OK,
I managed to get it to happen..
I wanted the script to go from 2230 down to 19
here is the code:
bytes_loaded = Math.round(this.getBytesLoaded());
bytes_total = Math.round(this.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
this.loadText = 2230-Math.round(getPercent*2211);//counts down from 100
trace(this.loadText)
if (bytes_loaded == bytes_total) {
this.gotoAndPlay(3);
}
