OnCollisonEnter C# , Tried everything >_< Not working!

Hi,

I am trying to destroy the player upon colliding with a game object cube named Death.
I attached rigid body to both the player and Death. Also added capsule collider to player and box collider to death . My player rigid body has kinematic and use gravity checked.I attached the script to Death.

The code I used was -

using UnityEngine;
using System.Collections;

public class Destuction : MonoBehaviour
{

void OnCollisonEnter(Collision col)
{
	if(col.gameObject.tag == "player")
	{
		Debug.Log ("You have been destroyed by death");
		Destroy(col.gameObject);
}

}
}

Found out what was wrong with it , the script was wrong actually collision what spelled collison , man I feel so stupid >_<
