hey guys, im making a game and my lives are going 5, 4 ,2, 1, so it skips 3 its strainge please help, here are what is prpbably inportant (btwmy health script is called HealthControl2 :

var health1 : Texture2D; //one live left
var health2 : Texture2D; //two lives left
var health3 : Texture2D; //3 left
var health4 : Texture2D; //4 left
var health5 : Texture2D; //5 left

static var LIVES = 5;

function Update () 
{
      switch(LIVES)
      {
            case 5:
                  guiTexture.texture = health5;
            break;

            case 4:
                  guiTexture.texture = health4;
            break;

            case 3:
                  guiTexture.texture = health3;
            break;

            case 2:
                guiTexture.texture = health2;
            break;

            case 1:
                 guiTexture.texture = health1;
            break;

            case 0:
                  //gameover script here
            break;
      }
}

and other script part:

 function OnTriggerEnter( hit : Collider )
    {
            if(hit.gameObject.tag == "fallout")
          {
          dead = true;
          //substract life here
          HealthControl2.LIVES -= 1;
          }
         if(hit.gameObject.tag == "enemyProjectile")
         {
                //gotHit = true;
                dead = true;
                HealthControl2.LIVES-= 1;
                //HealthControl.HITS += 1;
                Destroy(hit.gameObject);
         }
    }
