Why won't my player move

So i'm starting a new game (more of a benchmark for myself really though) to test how well I remember the material. So I had planned to test it bit by bit but I can't event get my player to move! I realize in a scroller you move the background mainly, not the player, but before I did that I tested to see if my player would move. He wouldn't. I'm not getting any errors, warning, output readings. Any ideas?

{

          import flash.display.MovieClip;

          import flash.events.Event;

          import flash.ui.Keyboard;

          import flash.events.MouseEvent;

          import flash.events.KeyboardEvent;

          public class Main extends MovieClip

          {

                    var vx:int;

                    public function Main()

                    {

                              init();

                    }

                    function init():void

                    {

                              //initilize variables

                              vx = 0;

                              //add Event Listeners

                              stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown);

                              stage.addEventListener(KeyboardEvent.KEY_UP, onKeyUp);

                              addEventListener(Event.ENTER_FRAME, onEnterFrame);

                    }

                    function onKeyDown(event:KeyboardEvent):void

                    {

                              if (event.keyCode == Keyboard.LEFT)

                              {

                                        vx = -5;

                              }

                              else if (event.keyCode == Keyboard.RIGHT)

                              {

                                        vx = 5;

                              }

                    }

                    function onKeyUp(event:KeyboardEvent):void

                    {

                              if (event.keyCode == Keyboard.LEFT || event.keyCode == Keyboard.RIGHT)

                              {

                                        vx = 0;

                              }

                    }

                    function onEnterFrame(event:Event):void

                    {

                     //Move the player

                    player.x +=  vx;

                    }

          }
