Loading an external swf and unloading the parent one

Question

Hi there i have made a navigation in flash and 3 buttons that load some external swf's. Problem is that when they load the parent swf keeps playing in the background. How can i make them play separately and make the navigation stage dissapear completely when they load?

I have attempted to use the same Loader but it doesnt replace it i dont know why.
var myLoader:Loader = new Loader();       
var myLoaderMain:URLRequest = new URLRequest("main1.swf");
var myLoaderQuiz:URLRequest = new URLRequest("quiz.swf");
var myLoaderAnimation:URLRequest = new URLRequest("athens_animation.swf");
var myLoaderVideo:URLRequest = new URLRequest("videogallery.swf");
videogallerybtn.addEventListener(MouseEvent.CLICK, videoFunc);
function videoFunc(curEvt:MouseEvent) {
          myLoader.load(myLoaderVideo);
          addChild(myLoader);
Quizbtn.addEventListener(MouseEvent.CLICK, quizFunc);
function quizFunc(curEvt:MouseEvent) {
          myLoader.load(myLoaderQuiz);
          addChild(myLoader);
Animationbtn.addEventListener(MouseEvent.CLICK, AnimationFunc);
function AnimationFunc(curEvt:MouseEvent) {
          myLoader.load(myLoaderAnimation);
          addChild(myLoader);
