Error in FPS Tutorial (help)

Hi…

Im trying this FPS Tutorial ...(Im noob): (Unity 3.4)

http://unity3d.com/support/resources/tutorials/fpstutorial

Well, I can`t continue ,because have this error in the Projectile.js

“No appropriate version of ‘UnityEngine.Object.Destroy’ for the argument list ‘(System.Type)’ was found”

here the script :

var explosion : GameObject ;

function OnCollisionEnter( Collision : Collision )
{
var contact : ContactPoint=Collision.contacts[0];

var rotation=Quaternion.FromToRotation(Vector3.up,contact.normal);
var InstantiatedExplosion : GameObject=Instantiate(explosion,contact.point, rotation );

Destroy(GameObject);
}.

Any help,please ???

It should be Destroy(gameObject);

ups ¡¡¡¡¡

Thanks
