as3 preloader help

programming flash
1

hi all

i have a preloader which loads everything up to the main page

next i wish to start preloading the games also, but not into content_mc (which holds the main as it takes a while to preload as it is, so i hide it and want to place another MC, between content_mc and the togglebutton, into which i can start loading the games, unsure how to go about this, here is the code which loads each page in turn into the content mc movieclip

any help much appreciated

import flash.display.*;
import flash.events.*;
import flash.net.URLRequest;
var myMovieClip:MovieClip = new toggleButton();
var games_mc:MovieClip = new MovieClip();
var content_mc:MovieClip = new MovieClip();
myMovieClip.x = 780.0;
myMovieClip.y =30.0;
addChild(content_mc);
addChild(games_mc);
addChild(myMovieClip);
var loadedSWF:Loader
var progressPercent:Number;
 function startLoad(SWFName:String):void {
    loadedSWF = new Loader();
 loadedSWF.contentLoaderInfo.addEventListener(Event.COMPLETE, gameLoaded);
 loadedSWF.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
    loadedSWF.load(new URLRequest(SWFName+".swf"));   
    
}
//track progress
function onProgressHandler(loadingProgress:ProgressEvent){
 var percent:Number = loadingProgress.bytesLoaded/loadingProgress.bytesTotal;
 
 progressPercent = Math.round((percent*100));
 preload_mc.gotoAndStop(progressPercent);
 preload_mc.myloadtext_txt.text=(progressPercent + " %")
  preload_mc.myloadbar_mc.scaleX = percent;
  preload_mc.mc_mask.height=(progressPercent * 3);
 preload_mc.ofBytes_txt.text = loadingProgress.bytesLoaded + " bytes";
 preload_mc.totalbytes_txt.text = loadingProgress.bytesTotal + " total bytes";
}
   
function gameLoaded(e:Event):void{
 
 removeChild(preload_mc);
 content_mc.addChild(loadedSWF);
 
 loadedSWF.contentLoaderInfo.removeEventListener(Event.COMPLETE, gameLoaded);
 loadedSWF.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, onProgressHandler);
}
function nextSWF(whichSWFName, removeSWF){
    if(whichSWFName == "startPages"){
 content_mc.removeChild(removeSWF.parent);
   addChild(preload_mc);
  startLoad("wholesite");
 }
  if(whichSWFName == "wholesite"){
        addChild(preload_mc);
  startLoad("explan0");
  }
 
}
