put this in:

 var health : float = 100;
 
 function Update()
 {
 
 var enemyComponent = GameObject.Find("enemy").GetComponent(enemyScript);
 
 if(Input.GetKeyDown(KeyCode.X))
 {
 
 health = health - enemyComponent.damage;
 
 }
 
 }

That means either: -There's no gameObject named "Enemy" in the children or -There's not an enemyScript object component on that gameobject

Don't do GameObject.Find in Update()!

And because there are many enemies and one player, you should have the instance enemyScript apply the damage to the playerScript.

 var playerScript : PlayerScript;
 function Awake () {
 playerScript = GameObject.FindWithTag("Player").GetComponent.<PlayerScript>();
 }

 function HitPlayer() {
 playerScript.health -= damage;
 }
