I need help with some health code:

var maxHealth : int = 100;
var currentHealth : int = 100;
function Update () {
	if(currentHealth < 0) {
		currentHealth = 0;
	}
	if(currentHealth > maxHealth) {
		currentHealth = 0;
	}
	if(maxHeath < 1) {
		maxHealth = 1;
	}
	if(currentHealth < 0) {
		Application.LoadLevel ("Gameover");
	}
}
function OnGUI() {
	if(GUI.Button ( Rect ( 150, 10, 100, 35) , "Health")) 
}
To me: it looks fine To Unity: 2 errors
The errors are:
Assets/PlayerHealth.js(19,1): BCE0044: expecting }, found ''.
Assets/PlayerHealth.js(18,63): BCE0043: Unexpected token: }.

Help please?

You aren’t doing anything after that if(GUI.Button… !! You need something to happen in response to the if condition - or if you don’t care and just want a button on screen drop the if( and add a ; on the end.

function OnGUI() {
    if(GUI.Button ( Rect ( 150, 10, 100, 35) , "Health"))  {
        //Do something if the button is pressed
    }
}

i have a script you could use, except it doesnt have game over:

using UnityEngine;
    using System.Collections;
    
    public class PlayerHealth : MonoBehaviour {
    		public int maxHealth = 100;
    		public int curHealth = 100;
    	
    		public float healthBarLength;
    
    	// Use this for initialization
    	void Start () {
    		healthBarLength = Screen.width / 2;
    	}
    	
    	// Update is called once per frame
    	void Update () {
    		AddjustCurrentHealth(0);
    	}
    	
    	void OnGUI() {
    		GUI.Box(new Rect(10, 10, healthBarLength, 20), curHealth + "/" + maxHealth);
    	}
    	
    	public void AddjustCurrentHealth(int adj) {
    		curHealth += adj;
    		
    		if(curHealth < 1)
    			curHealth = 1;
    		
    		if(curHealth > maxHealth)
    			curHealth = maxHealth;
    		
    		if(maxHealth < 1)
    			maxHealth = 1;
    		
    		healthBarLength = (Screen.width / 2) * (curHealth / (float)maxHealth);
    	}
    }
