Please HELP ME!..

var LevelText : GUIText;

var CoinsText : GUIText;

function Start () {

    playerManager = GameObject.Find("Player").GetComponent(PlayerManager);
    enemyHealth = GameObject.Find("Damage_trigger").GetComponent(Zombiedamage);
    EnemiesDeath = enemyHealth.Currenthealth <= 0;
}


function Update () {

	if(enemyHealth.Currenthealth <= 0){   
  	   playerManager.coins ++;
  	   playerManager.levels ++;
  	   CoinsText.ToString(enemyHealth.coins);
 }

     if(EnemiesDeath >= 15){

       LevelText.ToString(playerManager.levels);
 }

}

You have to declare the variables before refering to them.

var playerManager : PlayerManager;
var enemyHealth : Zombiedamage;

I’m not quite sure about the EnemiesDeath that you’re refering to. What exactly is that?
