Unexpected symbol ')', expecting identifier

Trying to follow along a tutorial from http://wiki.unity3d.com/index.php/Health_Bar_Tutorial and the code I’ve written keeps giving me this error for line 24, 37. Any ideas?

using UnityEngine;
using System.Collections;



public class healthbar : MonoBehaviour {

	private int maxHealth=100;
	public int curHealth=100;
	private float healthBarlength;
	// Use this for initialization
	void Start () {
		healthBarlength = Screen.width/2;
	}
	
	// Update is called once per frame
	void Update () {
		AdjustcurHealth(0);

}
	void onGUI(){
		GUI.Box(new Rect(10,10, healthBarlength, 20), curHealth + "/" + maxHealth);
}
	public void AdjustcurHealth(adj){
			curHealth += adj;

			if(curHealth < 0)
				curHealth = 0;
			if(curHealth > maxHealth)
				curHealth = maxHealth;
			if(maxHealth < 1)
				maxHealth = 1;

			healthBarlength = (Screen.width / 2) * (curHealth / (float)maxHealth);
}
}

Yep, line 24 is your problem.

public void AdjustcurHealth(adj){

You have to put a type for adj :

public void AdjustcurHealth(int adj){

I think you might want:

public void AdjustcurHealth(adj)

to be

public void AdjustcurHealth(int adj)
