Shooting works only when jumping not standing.

Hi All,

I'm having trouble getting my character to fire. it seems to fire when he jumps, but not while standing. I have attached my code to the zip file below:

This is the code I used:

---------------------------------------------

onClipEvent (load) {

    var gravity:Number = 0;

    var speed:Number = 5;

    var jumpHeight:Number = 13;

    var scale:Number = _xscale;

    this.gotoAndStop(2);

}

onClipEvent (enterFrame) {

    gravity++;

    _y += gravity;

    while (_root.ground.hitTest(_x, _y, true)) {

        _y--;

        gravity = 0;

    }

    if (Key.isDown(Key.SPACE)) {

        //

        gotoAndPlay("fire");

    }

    if (Key.isDown(Key.RIGHT)) {

        _x += speed;

        _xscale = scale;

        if (_root.ground.hitTest(_x, _y+3, true)) {

            this.gotoAndStop(1);

        } else {

            this.gotoAndStop(2);

        }

    } else if (Key.isDown(Key.LEFT)) {

        _x -= speed;

        _xscale = -scale;

        if (_root.ground.hitTest(_x, _y+3, true)) {

            this.gotoAndStop(1);

        } else {

            this.gotoAndStop(2);

        }

    } else {

        if (_root.ground.hitTest(_x, _y+3, true) && !Key.isDown(Key.LEFT) && !Key.isDown(Key.RIGHT)) {

            this.gotoAndStop(3);

        }

        if (Key.isDown(Key.SPACE)) {

            this.gotoAndPlay("fire");

        }

    }

    if (Key.isDown(Key.UP) && _root.ground.hitTest(_x, _y+3, true)) {

        gravity = -jumpHeight;

        this.gotoAndStop(2);

    }

}
