Csharp script parsing error

My script keeps saying parsing error
This is my script

using UnityEngine;
using System.Collections;

public class HealthBar : MonoBehaviour {
	public int maxHealth = 100;
	public int curHealth = 100;
	
	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
	
	}
	
	void OnGUI() {
		GUI.Box(new Rect(10, 10, Screen.width / 2 / (maxHealth / curHealth), 20, curHealth + "/" + maxHealth
	}
}

I don’t see something here that would generate a parsing error, but I do see errors on line 19. Change it to:

 GUI.Box(new Rect(10, 10, Screen.width / 2 / (maxHealth / curHealth), 20), curHealth + "/" + maxHealth);

i changed it to what you said but it still says parsing error.
using UnityEngine;
using System.Collections;

public class HealthBar : MonoBehaviour {
public int maxHealth = 100;
public int curHealth = 100;

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {

}

void OnGUI() {
	GUI.Box(new Rect(10, 10, Screen.width / 2 / (maxHealth / curHealth), 20, curHealth + "/" + maxHealth;
}

}
