function OnCollissionEnter not working

I am trying to make a pickup script in which when the player collides with the object the object gets destroyed.But this does not seems to work.Please help.

`var player : Transform;

function OnCollissionEnter(info : Collision )

{
if(info.gameObject.name == “player”)
{
Destroy (gameObject);
}

}`

It’s OnCollisionEnter() ← one “s”
