Nested mc button calling parent function

I have setup a video interface with a stock video player in the parent mc. In the same swf next to the player, I have a mc which is a video thumbnail chooser. The thumbnail buttons are located two levels down within this mc (nested within two mc) in order to facilitate the scrolling independent of the player. In the parent, where the video player lives, I placed a function:

function vid1(event:MouseEvent): void{
pubPlayer.source = ‘Steve480.flv’;

In the child mc where the thumbnail buttons are, I want to call the parent function like this:

vid1_btn.addEventListener(MouseEvent.CLICK, vid1);

None of my clips are externally loaded, just nested in the same swf. How can I talk up or down the movieclip ladder? Examples help me :slight_smile:
