Tiled Bg Problem

programming flash
1

Hi i am currently designing a flash section for my site and i needed the Bg to be tiled however when i use the tiling code the tiles are displayed correctly except for the fact that the tiles are now covering all the other elements on the stage so that alls i can see are tiles. the tile code i am using is below i would appreciate it if any1 knows how i might display the tiles behind all other elements on my stage thanks

stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;
 
stage.addEventListener(Event.RESIZE, tileBG);
 
var tile:Sprite;
 
function tileBG(event:Event=null):void {
 
    
    var oldTile:Sprite = tile;
 
    
    tile = new Sprite();
 
    
    tile.graphics.beginBitmapFill(new Pattern(0, 0));
    tile.graphics.drawRect(0, 0, stage.stageWidth, stage.stageHeight);
    tile.graphics.endFill();
 
    
    addChild(tile);
 
    
    if (oldTile != null && oldTile != tile) {
        removeChild(oldTile);
    }
}
 
tileBG();
