Getting script to stop after MC reaches x position

Question

working on scrolling panel and trying to get the function to stop scrolling when the last frame in one direction is the last left to be displayed so it doesn't keep scrolling infinitely off the stage. here's what I have
rightscroll_mc.addEventListener(MouseEvent.ROLL_OVER, scrollRight);
rightscroll_mc.addEventListener(MouseEvent.ROLL_OUT, rremoveFast);
function scrollRight(e:MouseEvent):void {
     this.addEventListener(Event.ENTER_FRAME, goRight);
function rremoveFast(e:MouseEvent):void {
     this.removeEventListener(Event.ENTER_FRAME, goRight);
if(grds11_mc.x < 335.2) {
     function goRight(e:Event):void {
          for(var i:int = 1; i<12; i++){
               this["grds"+String(i)+"_mc"].x-=15;
} else {
     this.removeEventListener(Event.ENTER_FRAME, goRight);

Answer 1

Try rewriting that so the the function contains the actionscript rather than the reverse....
function goRight(e:Event):void {
     if(grds11_mc.x < 335.2) {
          for(var i:int = 1; i<12; i++){
               this["grds"+String(i)+"_mc"].x-=15;
     } else {
          this.removeEventListener(Event.ENTER_FRAME, goRight);
