How to remove a function on the main timeline within a movie clip

How do you remove a function that is coded on a frame in the main timeline from within a movie clip?  I tried this, but no dice:

infoGraphicDisparity.addEventListener(MouseEvent.CLICK, fl_ClickToGoToScene);

function fl_ClickToGoToScene(event:MouseEvent):void

{

    parent.removeEventListener (Event.ENTER_FRAME, parent["enterFrameHandler"]);

    MovieClip(this.root).gotoAndPlay("disparity");

}

this is the event I am trying to remove:

stage.addEventListener(Event.ENTER_FRAME, enterFrameHandler);

any help would be appreciated as always.

Thanks!
