Refrencing A Movie Clip from a nested button

Hello all,

I created a movie clip that is driven by a button to tween onto the stage,there is a button inside the movie clip to tween the clip off the stage.

Is there a way to reference the movie clip from the nested button? This is the script that I wrote for it:

function dgaExit(event:MouseEvent):void {
var moveTween:Tween = new Tween(this.links_mc.pressn.dga_parent_mc, “x”, Strong.easeOut,295,-2862, 1, true);

I get the 1010 type error message:

Error #1010: A term is undefined and has no properties.
at site3_fla::dga_parent_37/dgaExit()

Thanks in advance!
