How to change levels, Identifier Expected error!

I am trying to change levels but it keeps saying “Identifier Expected”. When my player collides with a cube that has “is trigger” checked, I want to change the level to level2. But it doesn’t work. Can somebody please help me.
Ps. I have already attached the scenes in the build settings.Thanks.

using UnityEngine;
using System.Collections;

public class changeLevel : MonoBehaviour
{
	function OnTriggerEnter (other : Collider)
	{
		Application.LoadLevel ("level2"); 
	}
}

function OnTriggerEnter (other : Collider) // This here is javascript
{
Application.LoadLevel (“level2”);
}

This is Javascript. Not C# as you are trying to use.

void OnTriggerEnter(Collider other)
{
    Application.LoadLevel("level2");
}

You want that instead.
