click change scene help!

hi! I am trying to make it when people click on the game object it switches scene but with my current code it switches scene wherever i click

here is my code:

using UnityEngine;
using System.Collections;

public class Newlvl : MonoBehaviour {
void Update() {
if (Input.GetMouseButtonDown(0))
Application.LoadLevel(“lvl2”);

}

}

Try: Unity - Scripting API: MonoBehaviour.OnMouseDown()

And make sure to have the script on the gameObject you want to click.

Hey I am trying to do the same thing did it work??
