i got this problem, when i press 1 in keyboard, the function does not run, even i already declared it.

How do i solve this?

Here is the code:

public function Character() 
        {
            Constant.loaderMario.load(new URLRequest("mario.swf"));

            addEventListener(KeyboardEvent.KEY_DOWN, selectingPlayer);
        }

        private function selectingPlayer(event:KeyboardEvent):void
        {
            isoTextMario = new Word();
            isoTextChocobo = new Word();

            if (event.keyCode == Keyboard.NUMBER_1|| event.keyCode == 49)
            {
                Constant.marioSelected = true;

                if (Constant.marioSelected == true)
                {
                    isoTextMario.marioCharacter();
                    addChild(isoTextMario);
                }
            }

            else if (event.keyCode == Keyboard.NUMBER_2 || event.keyCode == 50)
            {
                Constant.chocoboSelected = true;

                if (Constant.chocoboSelected == true)
                {
                    isoTextChocobo.chocoboCharacter();
                    addChild(isoTextChocobo);
                }
            }
        }
