Need zombie to inflict damage

Ok so basicly i have this zombie script it works fine and every is right on it but i want to make the Zombie give damage to the first person controller and i want the first person controller to receive that damage can some one write the code on to my script.Im not to good at scripting so i dont know as much. Heres my script

var target : Transform; //the enemy's target var moveSpeed = 3; //move speed var rotationSpeed = 3; //speed of turning

var myTransform : Transform; //current transform data of this enemy var isNotDead : boolean = true; var health : float = 100; function Awake() { myTransform = transform; //cache transform data for easy access/preformance }

function Start() { target = GameObject.FindWithTag("Player").transform; //target the player

}

function Update () {

 if(health < 1){
 
     isNotDead = false;
     animation.Play("die");
     Destroy(gameObject, 1);
 }
 
 if(isNotDead){
 
     //rotate to look at the player
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
     Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
 
 
     
     var distance = Vector3.Distance(target.position, myTransform.position);
     if (distance < 3.0f) {
         animation.Play("attack1");
     }
     else{   
         //move towards the player
            myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
            animation.Play("walk1");
     }

 }

}

function ApplyDamage(dmg : float){

 health -= dmg;

}
