Changing level of swf being displayed?

Question

I currently have a movieclip that is loading in external swfs.  The movieclip that you click that loads the files externally is staying on top of the swf that gets loaded.  I'd like for it to stay under the swf and stay there so when the swf is unloaded it will remain there for further use. I know in as2 there were level0, level1, etc.  Is there anything in as3 for that or does anyone have any ideas how to fix this?
The Movieclip that is loading it is called Homeslideshow
Here is the class for Homeslideshow.as
package  {
     import flash.display.*;
    import flash.events.*;
     import flash.display.*;
     import flash.events.*;
     import flash.display.*;
     import FluidLayout.*;
     import flash.display.*;
     import flash.geom.*;
     import flash.media.*;
     import flash.events.*;
     import flash.ui.ContextMenuBuiltInItems;
     import flash.utils.*;
     import flash.xml.*;
     import flash.net.*;
     import flash.display.Sprite;
     public class Homeslideshow extends MovieClip{
          public function Homeslideshow() {
                      addEventListener(Event.ADDED_TO_STAGE, addedHandler);
            addEventListener(Event.REMOVED_FROM_STAGE, removedHandler);
                           slideshowimages_mc.one_mc.addEventListener(MouseEvent.CLICK, imageOne);
                              slideshowimages_mc.one_mc.buttonMode = true;
          private function addedHandler(e:Event)
               /* Apply the alignment to the content */
               var mc_homeslideshowParam = {
               //x:0.5,
               y:.7,
               //offsetX: -mc_homeslideshow.width/2,
               offsetY: -this.height/2
               new FluidObject(this,mc_homeslideshowParam);
          private function removedHandler(event:Event):void {
          private function imageOne(event:Event):void {
               var swfLoader:Loader = new Loader();
               MovieClip(root).holder_mc.addChild(swfLoader);
     var bgURL:URLRequest = new URLRequest("background1.swf");
     //swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadProdComplete);
     swfLoader.load(bgURL);
Also, here is the document class Main.as
     public class Main extends MovieClip
          private var mc_homeslideshow:Homeslideshow;
          public function Main()
               trace("works");
               mc_homeslideshow = new Intro();
               addChild(mc_homeslideshow);

check the displayobjectcontainer methods like addChildAt(), swapChildrenAt() etc
