scene_mc start at x = -550... x wide is 2164 px
now I have this and its working...
navL_mc.addEventListener(MouseEvent.MOUSE_OVER, navL_Over);
navL_mc.addEventListener(MouseEvent.MOUSE_OUT, navL_Out);
function navL_Over(e:MouseEvent){
          if(scena_mc.x == 0){
                              scena_mc.x == 0;
          else if(scena_mc.x <= -10){
                              scena_mc.x += 10;
                              navL_mc.addEventListener(Event.ENTER_FRAME, runL);
function runL(e:Event):void{
          if(scena_mc.x == 0){
                              scena_mc.x == 0;
          else if(scena_mc.x <= -10){
                              scena_mc.x += 10;
function navL_Out(e:MouseEvent){
          navL_mc.removeEventListener(Event.ENTER_FRAME, runL);
navR_mc.addEventListener(MouseEvent.MOUSE_OVER, navR_Over);
navR_mc.addEventListener(MouseEvent.MOUSE_OUT, navR_Out);
function navR_Over(e:MouseEvent){
          if(scena_mc.x == -1164){
                              scena_mc.x == -1164;
          else if(scena_mc.x >= -1154){
                              scena_mc.x -= 10;
                              navR_mc.addEventListener(Event.ENTER_FRAME, runR);
function runR(e:Event):void{
          if(scena_mc.x == -1164){
                              scena_mc.x == -1164;
          else if(scena_mc.x >= -1154){
                              scena_mc.x -= 10;
function navR_Out(e:MouseEvent){
          navR_mc.removeEventListener(Event.ENTER_FRAME, runR);
