I have a box\_mc on the stage and I create a btn inside the box\_mc.

the code in the class:

========================

btn.addEventListener (MouseEvent.MOUSE\_DOWN, handleMouseDown)

function handleMouseDown ($evt:MouseEvent):void  
{  
do something();  
}

=======================  
Also try:

box\_mc.btn.addEventListener (MouseEvent.MOUSE\_DOWN, handleMouseDown)

function handleMouseDown ($evt:MouseEvent):void  
{  
do something();  
}

========================  
Error: 1120: Access of undefined property btn.

NOT WORKING… I AM MISSING SOMETHING??

Thanks.
