[Solved]Object reference not set to instance of object in OnTriggerEnter

The game runs, but every time an enemy spawns, I get one of these errors on line 32, or the second "if" statement in the OnTriggerEnter function. The Sniper Rifle bullets don't register hitting the enemy, and I think this error has something to do with it. I have no idea why I get this error though.

 var health : float = 100.00;
 var SpawnPoint : Transform; 
 var Blood : Rigidbody;
 var Dead : Rigidbody;
 var Bullet : GameObject;
 var SniperBullet : GameObject;
     
 function Update() { 
     Bullet = GameObject.Find("Bullet 1(Clone)"); 
     SniperBullet = GameObject.Find("Bullet 2(Clone)");
     if(health <= 0.0)
         Death();
         }
         
 function Death() { 
     var Boom : Rigidbody;
     Boom = Instantiate(Dead, SpawnPoint.position, SpawnPoint.rotation);
     Destroy(gameObject);
     Points.Score += 10; 
         }    
             
 function OnTriggerEnter(other: Collider) { 
     var Spawn : Rigidbody;
     if(other.gameObject.tag == "Bullet")
         {
         health -= 25.0; 
         Points.Score += 5;
         Spawn = Instantiate(Blood, SpawnPoint.position, SpawnPoint.rotation);
         Destroy(Bullet); 
         }
     
     if(other.gamObject.tag == "SniperBullet") 
         {
         health -= 100.0; 
         Points.Score += 5;
         Spawn = Instantiate(Blood, SpawnPoint.position, SpawnPoint.rotation);
         }
     }
