Operator Cannot Be used with a left hand type 'System.type' and a right hand type 'int'

My script Keeps getting that 2 errors, when I use Health -= Damage, and when explaining the Variable Health,

#pragma strict

var Heath : int = 100;
var bullet : GameObject;
var damage : int;

function Update () 
{
	if (Health < 0)
	(
		DIE());
}

function OnTriggerEnter ( hit : Collider ) 
{
	if(hit.gameObject.tag == "Bullet")
	{
		bullet = hit.gameObject;
		TakeDamage ();
	}
}

function TakeDamage ()
{
	var BulletScript : Bullet = bullet.GetComponent("Bullet");
	damage = BulletScript.Damage;
	
	Health -= damage;
}

function DIE()
{
	Debug.Log("I'm Dead!");
	Destroy(gameObject);
}

So this is a perfect example of why following a “variable names are lower case initial letter” and “scripts are upper case first letter” really helps. You have a script called Health, you have a variable you thought was called “Health” but as @robertbu pointed out was called “Heath”. If you follow the rule then you would have received a much more meaningful error message about “heath” not being found rather than the compiler thinking you were trying to do something with your Health script.

On top of the fact that Health is spelled wrong, you did this in update:

function Update () 
{
    if (Health < 0)
    (
       DIE());
}

as far as my scripting knowledge goes, i’m pretty sure you cant use ‘(’ and ‘)’ to substitute for ‘{’ and ‘}’.

function Update (){
    if (Health < 0){
       DIE();
    }
}
