Hi everybody,

I’m making a flash CS4 presentation and I just made a navbar movieclip (grey rectangle) and put 6 buttons on each layer inside of it.

I put this navbar on the main movie timeline in a layer.

I keep getting this error (1120 access of undefined property) and the buttons simply don’t respond to the main timeline

Should I make a parent child reference ?

For example this code for the pause button won’t work:

pause\_btn.addEventListener (MouseEvent.CLICK, stopButtonClick);

function stopButtonClick (e:MouseEvent):void  
{

```
this.stop();

```

}

Any help would be great…
