Array index is out of range?

I have searched around a bit and found tons of awnsers but nothing that really helped me!

Here is my code:

 var Health : int = 50;
 var prefabBullet:Transform;
 var shootForce:float;
 var jump : GameObject;
 var smoke : GameObject;
 var smoking : int = 20;
 var HealthPoint : Texture[];
 var SpawnPoints : Transform[];
 var Deaths : AudioClip[];
 var Jump : AudioClip[];
 
 
 function Update () {
     if(Health <= 0){
         var instanceBullet = Instantiate(prefabBullet, transform.position, Quaternion.identity);
         instanceBullet.rigidbody.AddForce(transform.forward * shootForce);
         death();
         Health = 50;
         
     }
     
     if(Health <= smoking)
         smoke.active = true;
         
     if(Health >= smoking)
         smoke.active = false;
     
     if (Input.GetButtonDown("Jump")){
         audio.clip = Jump[0];
         audio.Play();
         jump.active = true;
     }
     if (Input.GetButtonUp("Jump")){
         audio.clip = Jump[0];
         audio.Stop();
         jump.active = false;
     }
 }
 
 
 function OnCollisionEnter(collision : Collision){
     if(collision.gameObject.tag == "Bullet"){
         var randDamage = Random.Range(1, 5);
         var damage = randDamage;
         
         switch(damage){
             case 1:
                 Health -=1;
             break;
             case 2:
                 Health -=2;
             break;
             case 3:
                 Health -=3;
             break;
             case 4:
                 Health -=4;
             break;
             case 5:
                 Health -=5;
             break;
         }
     }
 }
 
 
 function OnTriggerEnter(other : Collider){
     if(other.tag == "Health"){
         Health += 1*Time.deltaTime;
         
         if(Health >= 50){
             Health = 50;
         }
     }
 }
 
 
 function OnGUI() {
     if(Health <= 50){
         GUI.DrawTexture(Rect(0.0f,0.0f,Screen.width,Screen.height), HealthPoint[5]);
     }
     if(Health <= 40){
         GUI.DrawTexture(Rect(0.0f,0.0f,Screen.width,Screen.height), HealthPoint[4]);
     }
     if(Health <= 30){
         GUI.DrawTexture(Rect(0.0f,0.0f,Screen.width,Screen.height), HealthPoint[3]);
     }
     if(Health <= 20){
         GUI.DrawTexture(Rect(0.0f,0.0f,Screen.width,Screen.height), HealthPoint[2]);
     }
     if(Health <= 10){
         GUI.DrawTexture(Rect(0.0f,0.0f,Screen.width,Screen.height), HealthPoint[1]);
     }
     if(Health <= 1){
         GUI.DrawTexture(Rect(0.0f,0.0f,Screen.width,Screen.height), HealthPoint[0]);
     }
 }
 
 
 function death(){
     AudioSource.PlayClipAtPoint(Deaths[ Random.Range(0, Deaths.Length)], transform.position, 2.0f);
      i = Random.Range(0, SpawnPoints.Length);
      transform.position = SpawnPoints[i].position;
     transform.rotation = SpawnPoints[i].rotation;
 }
