Enemy health drops but not if first enemy lives, how do i change that?

My script works perfectly except, if enemy1 hasnt been "killed"(when health = 0, it dies.) enemy2 cant be attacked. I need to be able to reduce any enemies health when pressing the Attack button and enemy is inside the attackThreshold..

like i said this all works, just i cant kill enemy2 unless enemy1 is dead. Anyone have any idea what i can do to achieve this?

using UnityScript by the way.

This is my EnemyScript.js

 private var enemyMaxHp : float;
 private var enemyCurHp : float;
 var startingHealth : float = 100.0;
 var target : Transform;
 var moveSpeed = 10;
 var rotationSpeed = 10;
 var attackThreshold = 10; //distance in which to attack
 var giveUpThreshold = 51; //how close you get before enemy start chase
 var attackRepeatTime = 100; //attack delay
 private var damage;
 private var chasing = false;
 var attackTime;
 var myTransform : Transform; //current transform data of the enemy
 private var distance;
 var idle;
 myTransform = transform; //cache transform data for easy access/performance
 
 function Awake(){
 attackTime = Time.time;
 myTransform = transform; //cache transform data for easy access/performance
 }
 
 function Start(){
  enemyMaxHp = startingHealth;
  enemyCurHp = startingHealth;
     target = GameObject.FindWithTag("Player").transform; //target the player
 }
 
 
 function Update () {
 distance = (target.position - myTransform.position).magnitude;
     if (enemyCurHp > enemyMaxHp){
         enemyCurHp = enemyMaxHp;
     }
     if (enemyCurHp < 0){
         enemyCurHp = 0;
     }
     
     if (enemyCurHp < 1){
     Destroy(gameObject);
     }
             
         if(chasing){
             Chase();
         }
         
         if(distance > giveUpThreshold) { //give up if too far away
             chasing = false;
             idle = true;
             }
         
         if(idle){
             //Idle animation.
         }
         //not currently chasing
         //start chasing if target comes close
         if(distance < giveUpThreshold) {
         chasing = true;
         }
         
         if(distance < attackThreshold){
         Attack();
         }
 }
 
 function ApplyEnemyDamage (enemyDamage : float) {
 distance = (target.position - myTransform.position).magnitude;
     if(distance < attackThreshold){
     enemyCurHp = enemyCurHp - enemyDamage;
     Debug.Log(enemyCurHp);
     }
 }
 
 function Attack () {
 chasing = false;
     if(attackTime < Time.time){
     // Calls the function ApplyDamage with a value of 5
     gameObject.FindWithTag("Player").SendMessage ("ApplyDamage", 5.0);
     attackTime = Time.time + attackRepeatTime;
     }
 }
 function Chase(){
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation, Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed * Time.deltaTime);
     myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime; //move to player
 }

 

this is the attack inside of my PlayerScript.js

 function PlayerAttack () {
 chasing = false;
     if(attackTime < Time.time){
     // Calls the function ApplyDamage with a value of 5
     gameObject.FindWithTag("Enemy").SendMessage ("ApplyEnemyDamage", 10.0);
     attackTime = Time.time + attackRepeatTime;
     }
 }
