Can't target main stage from dynamically loaded swf...

Question

A part of the Flash app. I'm working on right now does the following -
Main stage loads an external swf using the following function:
function loadAsset(evt:String):void{
var assetName:String = evt;
if (assetName != null){
  var assetLdr:Loader = new Loader(); 
  var assetURL:String = assetName; 
  var assetURLReq:URLRequest = new URLRequest(assetURL); 
  assetLdr.load(assetURLReq); 
  assetLdr.contentLoaderInfo.addEventListener( Event.INIT , loaded) 
  assetLdr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, displayAssetLoaderProgress);  
  function loaded(event:Event):void { 
   var targetLoader:Loader = Loader(event.target.loader); 
   assetWindow.addChild(targetLoader);
The externally loaded swf loads another external swf into itself using the following function:
function loadQuiz(evt:String):void{   
var quizName:String = evt;
if (quizName != null){
  var quizLdr:Loader = new Loader();
  var quizURL:String = quizName;
  var quizURLReq:URLRequest = new URLRequest(quizURL);
  quizLdr.load(quizURLReq);
  quizLdr.contentLoaderInfo.addEventListener( Event.INIT , loaded)       
  quizLdr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, displayQuizLoaderProgress); 
  function loaded(event:Event):void {
   var targetLoader:Loader = Loader(event.target.loader);
   quizWindow.assetLoader.addChild(targetLoader);     
Everything loads fine, but from the quizWindow.assetLoader.addChild(targetLoader) level, I want to send a message/fill in a dynamic text box on the Main Stage. I have been "parenting" my brains out and I'm not sure how to communicate with that level.
can anyone show me the proper path or method based off the above, or have a suggestion?

Andrei1,
Thanks again for your help. I was finally able to get the solution you posted below to work for me.
Much appreciation,

"In your loaded movie write:
function traceMyself(e:MouseEvent):void{
     dispatchEvent(new Event("I_WANT_TEXT"));
function writeText(text:String):void {
     xmlFileName1.text = text;
In the top movie that loads external swfs something like that:
loadedSwf.addEventListener("I_WANT_TEXT", onTextRequest, true);
function onTextRequest(e:Event):void {
     Object(e.target).writeText(tQuizXmlFile1.theQuizXmlFile.text);
This way these two entities are independent and, most importantly, don't care who is the parent or grandparent."
