Spawn Script not working on iPhone?

So I have the script below. It works fine when i test it on my game, on my computer. But when I put it on an actual Iphone it stops spawning completely.

  #pragma strict
  //Attach to empty object, in front of barrel
  var projectile : Rigidbody;
  var speed = 20;
  var fireRate = .5;
  var mySound : AudioClip;
 
  function React () {
  InvokeRepeating("Fire",1,fireRate);  
  }
  function Fire()
  {
      audio.PlayOneShot(mySound);
      var instantiatedProjectile : Rigidbody = Instantiate(
      projectile, transform.position, transform.rotation );
     instantiatedProjectile.velocity =
     transform.TransformDirection(transform.forward * speed);
     Physics.IgnoreCollision( instantiatedProjectile. collider,
     transform.root.collider );
     Physics.IgnoreCollision(gameObject.FindWithTag("Whatever").transform.collider , this.collider);
    }
  script 2
  this code triggers it.

  #pragma strict
  function OnCollisionEnter(col : Collision) {
  if(col.gameObject.name == "Gun"){
  gameObject.Find("SpawnPoint").SendMessage("React");
  }
  }
