add is not a member of UnityEngine.Component

Unity Engine
1

I know many of members have asked this question, I have tried to apply their solutions but they are not working for me. I have an object with this script :

function OnCollisionEnter (col : Collision) {
 if (col. gameObject.name == "Player"){
  var go = GameObject.Find("Player");
  go.GetComponent(testToAdd).add();
  print("You have the key"); 
  Destroy(gameObject); 
 }

}

When Player hits the object, object gets destroyed and calls a function “add” in script “testToAdd.js”, whitch is attached to Player. I’m using Unity 3.2 Pro Trial and try to build game on iPad, when receive the error from topic…

var script : testToAdd;

script = go.GetComponent(testToAdd);
script.add();

Edit: also, you don’t really need to call GameObject.Find(“Player”) here, because you already have a reference to the player in the form of col.gameObject. So I suggest you replace that with:

var go = col.gameObject;

Just because GameObject.Find() is much, much slower.
