Hi I have button (instance name-test1) on main time line. and following as on class file (main.as) works fine.

> if(String(\_xml.setup.buttons.music.@state) == “enabled”){  
> test1.buttonMode = true;  
> test1.mouseEnabled = true;  
> test1.addEventListener(MouseEvent.CLICK, myBtnClicked);

function myBtnClicked(e:MouseEvent):void {  
var url:String = “[http://www.example.com/](http://www.example.com/)”;  
var request:URLRequest = new URLRequest(url);  
try {  
navigateToURL(request, ‘\_blank’);  
} catch (e:Error) {  
trace(“Error occurred!”);  
}  
}

Now for some reason I need to place the symbol inside another symbol2 (symbol2 is on maintimeline) but code is not working anymore and getting error

1120: Access of undefined property test1.

Thanks…needs to fix that
