Enter Frame Loop is updating the enemy class but enemy is not moving

Question

    public function Goblin()
    {
        move = true;
        nTimer = 0;
        speed = 1;
        this.addEventListener(Event.ADDED_TO_STAGE, onAdd)
    }

    private function onAdd(e:Event):void 
    {
        trace("added Goblin");
        removeEventListener(Event.ADDED_TO_STAGE, onAdd);
    }

    public function goblinLoop() 
    {
        trace("yes");
        //trace(nTimer);

        this.x -= 4;


    }

This is the enemy class, and you can see I'm not using an enter frame to move it. Instead, from the main class I am...

    private function updatePlayer():void 
    {
        character.keyListner();
        character.movementChar();
        goblin1.goblinLoop();
        goblin2.goblinLoop();

    }

What I don't understand is that it traces "yes" in the output panel, but the goblin does not move, despite the function being called.

I have gone back to enterFrame for now, I will use an update method when I have developed the skills and researched more in to enterFrames any why not to use them (multi threaded games).

Thank you for your input.
