How to reference a bitmap?

[kiwir0b]

Hi

I'm having problems removing a bitmap from the stage from within a function. Apparently I need to reference the bitmap first. How do I reference the following bitmap?

The bitmap code I'm using:

function ScreenShot():void {
    addChild(snapShot(LoadedCam)); 
    function snapShot(mc:DisplayObject):Bitmap {
        var m:Matrix = new Matrix(Flip,0,0,1,240,400);        
        var TempPhoto:BitmapData = new BitmapData(480,800,true,0x00000000);
        TempPhoto.draw(LoadedCam,m);
        var bmp:Bitmap = new Bitmap(TempPhoto);
        return bmp;
    }
} 

And the function code I'm using:

function RetakeButton(event:MouseEvent):void { 
    TempPhoto.dispose();
} 

Thanks in advance!
