RemoveChild issue

Question

Hi All,
Got this code loading thumbs, and when their clicked loads a
bigger image etc...
function xmlLoaded (e:Event):void {
xml = XML(e.target.data);
images = xml.image;
for(var i:uint=0; i<images.length();i++){
var thumb:MovieClip = new MovieClip();
var thumbLoader:Loader = new Loader();
thumb.x = 65*i + spacing;
thumb.y = 370;
thumb.src = images[counter].@url;
thumb.mouseChildren = false;
thumb.buttonMode = true;
thumbLoader.load(new URLRequest(images[counter].@thumb));
addChild(thumb);
thumb.alpha = 0;
TweenMax.to(thumb, 1, {alpha:1, ease:Sine.easeIn});
thumb.addChild(thumbLoader);
thumbLoader.x = 24;
thumbLoader.y = -14;
thumb.addEventListener(MouseEvent.CLICK, clickedThumb);
counter++;
loader.load(new URLRequest(images[0].@url));
Problem happens with the following code - I go into
fullScreen and want to either hide the thumb etc... or remove it:
masker.addEventListener(MouseEvent.CLICK, fullScreen);
function fullScreen(MouseEvent):void
thumb.visible = false; // do not work
removeChild(thumb); // do not work
stage.displayState = StageDisplayState.FULL_SCREEN;
masker.x=0;
masker.y=0;
masker.width=stage.stageWidth;
masker.height=stage.stageHeight;
StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;
masker.buttonMode = true;
Hope someone can provide an answer to this, as it's driving
me BONKERS ;) It's got to be down to how I am referring to it, the
path.
Kind Regards,

Answer 1

I can see a few possible problems. One is that if you want to
reference a variable you create from multiple functions it needs to
be declared outside both functions. Such as reference 1 below.
Another is if you are creating many objects creating the same
variable you should add them to an array to be able to access them
later as below in reference 2.
Note sure if these may help, but thought I would throw them
out there.
