OK, this has to be simple, but I can’t seem to find a solution. I am generating a list of buttons (thumbnails). it’s displaying correctly. But how do I know which button I pressed on? I need to know this information so, if I press the second thumbnail it displays the correct larger image or goes to the right frame.

var btnNum:uint = 8;  
var spacing:Number = 10;

var cols:Number = 3;  
//x and y controllers  
var ii:Number = 0;  
var yax:Number = 5;

var navBar:Sprite = new Sprite();  
addChild(navBar);  
var btn:MovieClip;

for(var i:uint = 0; i \< btnNum; i++) {  
btn = new Btn();  
btn.x = spacing + ii \* (btn.width + spacing);  
btn.y = yax;

```
var thumb = new Loader();
btn.addChild(thumb);
thumb.load(new URLRequest("images/thumb/1.jpg"));

btn.addEventListener(MouseEvent.CLICK, onTraceName);
btn.addEventListener(MouseEvent.ROLL_OVER , fadeMe);
btn.addEventListener(MouseEvent.ROLL_OUT , fadeOutMe);

navBar.addChild(btn);
ii++
if (ii == cols){
    yax = btn.y + (btn.height + 5);
    ii = 0;
    
}

```

}

var bg:MovieClip = new NavBarBack();  
bg.width = cols \* (btn.width + spacing);  
bg.width += spacing;  
bg.height = (btnNum / cols) \* (btn.height + 7);  
trace(btn.height);  
navBar.addChildAt(bg,0);

navBar.x = (navBar.stage.stageWidth - navBar.width)/2  
navBar.y = 20;

function onTraceName(EVENT){  
trace(EVENT.target.name);  
}

function fadeMe(EVENT){  
EVENT.target.alpha = .5;  
}

function fadeOutMe(EVENT){  
EVENT.target.alpha = 1;  
}
