Cube won't rotate in roll-a-ball tutorial

hello

I’m trying to do the roll-a-ball tutorial and the cube won’t rotate

I believe I wrote the code as the video instructed and the cube still won’t budge.
can anyone help?

using UnityEngine;
using System.Collections;

public class Rotator : MonoBehaviour
{

// Update is called once per frame
void Update () 
{
	transform.Rotate(new Vector3(15, 30, 45) * Time.deltaTime);
}

}

Check did you attached your Rotator script to your cube?

I had the same problem as sider87, but my cube had the script attached.
Here is my script
using UnityEngine;
using System.Collections;

public class Rotator : MonoBehaviour {

// Update is called once per frame
void Update () 
{
	transform.Rotate (new Vector3 (15, 30, 45) * Time.deltaTime);

}

}
