Action Script 3 Percentage Preloader

Question

Here is my code:
import flash.display.*;
this.stop();
var ld:Loader = new Loader();
ld.contentLoaderInfo.addEventListener(Event.COMPLETE, addSWF);
ld.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, preloaderHandler);
ld.load(new URLRequest("pictures.swf"));
function preloaderHandler(event:ProgressEvent):void{     
     var pcent:Number=event.bytesLoaded/event.bytesTotal*100;      
     preloadBar.scaleX=pcent/100;     
     preloadTxt.text=int(pcent)+"%";
function addSWF(event:Event):void {     
     addChild(ld);
What I want to do is have it only preload 10% of the file, then to start to play while it loads the rest of the file in the background. As of right now it loads 100% of the file. I know that it does this on the 5th line:
ld.contentLoaderInfo.addEventListener(Event.COMPLETE, addSWF);
But, I can't figure out how to put (Event.10%, addSWF);
Any help would be appreciated.

Unfortunately that didn't work either. I changed the code to include a '}'
import flash.display.*;
this.stop();
var ld:Loader = new Loader();
ld.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, preloaderHandler);
ld.load(new URLRequest("pictures.swf"));
function preloaderHandler(event:ProgressEvent):void{    
    var pcent:Number=event.bytesLoaded/event.bytesTotal*100;     
    preloadBar.scaleX=pcent/100;    
    preloadTxt.text=int(pcent)+"%";
if (pcent == 10){
     addChild(ld);
The code seems sound, but "addChild(ld);" is never called.
