removeChildren on page when going to next frame?

programming flash
1

Whenever I go to the next frame in my Flash website the Children I had on the previous frame still show up on the next and then every other page after that.

I’ve tried to used stage.removeChild but it still isn’t doing the trick.


// Tiesto external loading for progress bar and image.
import fl.controls.ProgressBar;
import fl.controls.Button;

var my_loader:Loader = new Loader();

var my_btn:Button = new Button();
my_btn.label = "Tiesto!";
my_btn.x = 200;
my_btn.y = 340;
addChild (my_btn);

var my_pb:ProgressBar = new ProgressBar();
my_pb.source = my_loader.contentLoaderInfo;
my_pb.x = 100;
my_pb.y = 340;

my_btn.addEventListener(MouseEvent.CLICK, startLoading);
function startLoading(e:MouseEvent):void
{
    my_loader.load(new URLRequest("tiesto.jpg"));
    addChild(my_pb);
    removeChild(my_btn);
    my_btn=null;
}

my_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, finishLoading);
function finishLoading(e:Event):void
{
    my_loader.x = 100;
    my_loader.y = 340;
    addChild(my_loader);
    removeChild(my_pb);
    my_pb = null;
}


// Calvin Harris external loading for progress bar and image.   
import fl.controls.ProgressBar;
import fl.controls.Button;

var my_loader2:Loader = new Loader();

var my_btn2:Button = new Button();
my_btn2.label = "Calvin Harris!";
my_btn2.x = 200;
my_btn2.y = 680;
addChild (my_btn2);

var my_pb2:ProgressBar = new ProgressBar();
my_pb2.source = my_loader2.contentLoaderInfo;
my_pb2.x = 200;
my_pb2.y = 680;

my_btn2.addEventListener(MouseEvent.CLICK, startLoading2);
function startLoading2(e:MouseEvent):void
{
    my_loader2.load(new URLRequest("Calvin-Harris.jpg"));
    addChild(my_pb2);
    stage.removeChild(my_btn2);
    my_btn2=null;
}

my_loader2.contentLoaderInfo.addEventListener(Event.COMPLETE, finishLoading2);
function finishLoading2(e:Event):void
{
    my_loader2.x = 100;
    my_loader2.y = 680;
    stage.addChild(my_loader2);
    stage.removeChild(my_pb2);
    my_pb2 = null;
}   

next_btn.addEventListener(MouseEvent.CLICK, removeAllChildren);
function removeAllChildren(e:MouseEvent):void 
{
    removeChild(my_loader);
    stage.removeChild(my_btn);
    removeChild(my_loader2);
    stage.removeChild(my_btn2);
}

Help would be much appreciated.
