Bullet glitch?

I am not sure whats wrong with the AS. It has something to do with my AS thats on the bullet. When I test the movie out, a random bullet is going horizontaly across my screen and then when I press control (fire button) no bullets will go. Any help would be appreciated.

AS on my bullet:


onClipEvent (load) {
  bulletMoveSpeed=20;
  this._x=_root.spaceship._x+90; 
  this._y=_root.spaceship._y;
}
onClipEvent (enterFrame) {
  this._x+=bulletMoveSpeed;
  if (this._x>600){
	this.removeMovieClip();
  }
}
