Script doesn't find other script

I am instantiating a prefab when I press "T" and when I walk over it it is supposed get destroyed, which it does. But the issue is that the instantiated prefab doesn't assign the script that it changes a variable of. How do I make it so that it assigns the script once it has been instantiated?

Here's my script: var Tact : ThrowTact;

 function Start () {
 
 
     
    }
    
    function Update () {
   
    
    Tact = GetComponent(ThrowTact);
    
    
    
    }
    
    
 function OnTriggerEnter (Other : Collider) {
     
 if(Other.gameObject.tag == "Player"){
     
     
 
 
 Destroy(gameObject);
 Tact.HasTact = true;
    
 
    }
    
    
    
 }
