Simple loop question

I can’t seem to get my movie clips to display evenly on the x axis… here is what I have

var mb:MovieClip;

		for (var i:int=0; i<btnArray.length; i++)
		{
			mb = new menuButton;
			mb.menuText.autoSize = TextFieldAutoSize.LEFT;
			mb.menuText.text = btnArray*.name;
			
			mb.buttonMode = true;
			mb.mouseChildren = false;
			mb.addEventListener(MouseEvent.MOUSE_OVER, mouseActions);
			mb.addEventListener(MouseEvent.MOUSE_OUT, mouseActions);
			mb.addEventListener(MouseEvent.CLICK, mouseActions);

//This is the part that is not working…
btnArray*.x =i * 10;

			btnArray* = mb;
			trace(btnArray*.x);
			
			this.addChild(mb);
		
		
		}

All the objects just pile on top of one another, I know I’m missing a simple piece of the equation, but I just can’t seem to figure it out…

Thanks in advance!!
