gameobject teleports to random location

I am trying to make a game where a gameobject is constantly moving towards you, and the only way to keep it away if by shining it with a flashlight. I have a cube attached to the flashlight as a collider. I've been configuring this script for hours, but it still doesn't move the gameobject when the light collider hits it

Here is the script:

 var destination:Vector3;
 
 function OnTriggerEnter(other : Collider) 
 { 
     if(other.tag == "EvilFace") 
     {
         destination=Vector3(Random.Range(0,300),
                                        Random.Range(0,300),Random.Range(0,300));
         other.transform.position = destination; 
         audio.Play(); 
     }
 }
