Clip running wild. Help!

Help! I can’t find anyway to stop this thing.

The clipevent moves the movieclip which is named mymovie_mc (instance) right of the bottom of the stage and keeps going. I have tried all the items following the // but none of the have any effect on stopping this thing. How do I stop this thing. I have searched and found a lot of data on stopping the onEnterFrame, but can’t find anything on onClipEvent.

onClipEvent (enterFrame) {

_y += 5;

if (_y > Stage.height) {

// delete this.onClipEvent(enterFrame);
// delete this.onEnterFrame;
// this.removeMovieClip();




put that instead of the commented lines.
