AS3 Setting width and height of a Sprite Container

Ok, my mind is boggling over this issue im having. I know this might seem like such an easy issue and I can't understand why I cant figure it out but none the less I can't and I've just about given up. Here's the issue:

I have a sprite container which is supposed to hold a bunch of thumbnails to videos. I am able to populate the container with all the videos and the whole works but obviously if I add a bunch of videos its going to exceed the size of the flash document so I need to add a UIScrollBar (which I did) now the scrollbars target is set to the container but isnt allowing me to scroll and if im correct this is because the container doesnt have a set height. So Im trying to set the height of this container but the second I try setting the height or even width all my thumbnails I used to be able to see are gone! It's as if the size is being set to 0 when its not I've even tried to set it to a specified size just to test and nothing. Anyways heres my code if anyone can help out I'd really appreciate it! Thanks in advance!


import fl.controls.UIScrollBar; 

var videoList:XMLList;
var numVideos:Number;
var current_Video:Number = 0;
var video_position:Number;
var video_paused:Boolean;
var xmlPlaylist:String;

//XML File setup
var playlist_xml:XML;
var myLoader:URLLoader = new URLLoader();

//Playlist setup
var thumb_width:Number;
var thumb_height:Number;
var thumbs_x:Number;
var thumbs_y:Number;
var main_container:Sprite;
var thumbs:Sprite;
var scrollbar:UIScrollBar;

//Loader Data
this.loaderInfo.addEventListener(Event.COMPLETE, loaderComplete);
function loaderComplete(e:Event):void
{
    var myQueryStrings = this.loaderInfo.parameters;
    xmlPlaylist = myQueryStrings.pList;

    myLoader.load(new URLRequest(xmlPlaylist + "?uniq=" + new Date().getTime()));
}

myLoader.addEventListener(Event.COMPLETE, processXML);
function processXML(e:Event):void {
    playlist_xml = new XML(e.target.data);

    numVideos = playlist_xml.video.length();
    videoList = playlist_xml.video;

    thumb_width = playlist_xml.@thumb_width;
    thumb_height = playlist_xml.@thumb_height;
    thumbs_x = playlist_xml.@thumbs_x;
    thumbs_y = playlist_xml.@thumbs_y;

    current_Video = Math.round(Math.random()*(numVideos-1))+1;
    current_Video--;

    startPlayer();
}

function startPlayer()
{
    makeContainers();
    callThumbs();
    setVideo(current_Video);
}

function makeContainers():void
{
    main_container = new Sprite();
    addChild(main_container);

    thumbs = new Sprite();
    thumbs.addEventListener(MouseEvent.CLICK, playVideo);
    thumbs.addEventListener(MouseEvent.MOUSE_OVER, onOver);
    thumbs.addEventListener(MouseEvent.MOUSE_OUT, onOut);
    thumbs.x = thumbs_x;
    thumbs.y = thumbs_y;

This is where the Issue is: (If i comment out this code it displays the thumbnails)


    thumbs.width = thumb_width;
    thumbs.height = (thumb_height + 11) * 3;


    thumbs.buttonMode = true;
    main_container.addChild(thumbs);

    scrollbar = new UIScrollBar();
    scrollbar.x = thumbs_x + thumb_width + 2;
    scrollbar.y = thumbs_y;
    scrollbar.setSize(25, (thumb_height + 11) * 3);
    scrollbar.visible = true;
    scrollbar.scrollTarget = thumbs;
    main_container.addChild(scrollbar);
}

function callThumbs():void
{
    for (var i:Number = 0; i (less than) numVideos; i++) //For some reason Stack Overflow isnt allowing me to put the symbol less than so i just typed it in...
    {
        var thumb_url = videoList[i].@thumb;
        var thumb_loader = new Loader();
        thumb_loader.name = i;
        thumb_loader.load(new URLRequest(thumb_url));

        thumb_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, thumbLoaded);

        thumb_loader.y = (thumb_height + 11) * i;
    }
}

function thumbLoaded(e:Event):void
{
    var my_thumb:Loader = Loader(e.target.loader);
    thumbs.addChild(my_thumb);
}

function playVideo(e:MouseEvent):void
{
    setVideo(e.target.name);
}

function onOver (e:MouseEvent):void
{
    var my_thumb:Loader = Loader(e.target);
    my_thumb.alpha = 0.5;
}

function onOut (e:MouseEvent):void
{
    var my_thumb:Loader = Loader (e.target);
    my_thumb.alpha = 1;
}

function setVideo(current_Video)
{
    var display:String = videoList[current_Video].@title;
    var video:String = videoList[current_Video].@url;

    txt_Display.text = display;
    flvPlayer.source = video;
}

stop();
