overlap numbers

Hi, I have a problem, I just overlap the number. Are on top of each other. As in the picture

This is the link of the photo: http://www.subeimagenes.com/img/sin-titulo-1046356.png

This is the script:

 var PuntosJugador1:int = 0;
 
 
 function OnCollisionEnter (col : Collision) {
 
 if (col.gameObject.name == "Pelota")
     
 PuntosJugador1 += 1;
 
 Debug.Log("El puntaje del jugador 1 es " +  PuntosJugador1);
 
 
 }
 
 function OnGUI () {
 
 
 GUI.Label(Rect(0,0,100,100),"" + PuntosJugador1);
 
 
 }

Thanks !
