movieclip resume after scrubber (slider) use

[Lars!]

Hi everyone, i have this problem and i just cant seem to find what is wrong with my code. I have build a project where i have a slider that controls the main timeline, to scroll through my movie, but after i pull it (which works fine) the timeline stops, and i cant get it to resume. Here is my code

slider_mc.knob_mc.addEventListener(MouseEvent.MOUSE_DOWN, onDragKnob);

stage.addEventListener(MouseEvent.MOUSE_UP, onReleaseKnob);

slider_mc.knob_mc.buttonMode=true;

function onDragKnob(myEvent:Event):void {
slider_mc.knob_mc.startDrag(false, new Rectangle(0,0,175,0));
slider_mc.knob_mc.addEventListener(Event.ENTER_FRAME, onScrubMovie);


}

function onReleaseKnob(myEvent:Event):void {
slider_mc.knob_mc.stopDrag();
slider_mc.knob_mc.addEventListener(Event.ENTER_FRAME, onPlay);
//gotoAndPlay(1);
//play();



}

function onScrubMovie(myEvent:Event):void {
var playHead:int=Math.round((slider_mc.knob_mc.x/175*this.totalFrames)+1);
gotoAndStop(playHead);

trace (playHead);


}

function onPlay(myEvent:Event):void {
	play();  

}

Im not that sharp with as3, so i hope you can tell me why the movie wont resume
