Noob question: Shared listeners

I have this code:


var numOfLinks = 4
for (var i=0; i<numOfLinks; i++) {
var breakImg = new breaker();
breakImg.x = 0
breakImg.y = stage.stageHeight/numOfLinks*i
addChild(breakImg);
breakImg.addEventListener(Event.ENTER_FRAME, mover);
}

function mover(e:Event){
	var thim:MovieClip=MovieClip(e.target);
	thim.x++
}

I want all of them to move to the right but it keeps returning this error:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.text::TextField@ebc1629 to flash.display.MovieClip.
at as3_navigation_fla::MainTimeline/texterMover()

I just need all of the movie clips to have the same listener

Can anyone help
