Script errors. C# (C sharp)

Ok so I just got the Minecraft Starter Kit for Unity 3d and it went to put a script on a block and I got this error:

Can’t add script.
Can’t add script.scrpit must Derive from Mono Develop.

The script is C# (C Sharp) Thanks :smiley:
P.S. I got this package from the Unity 3d website, so it shouldnt be doing that right ??

I believe that that may mean that you’re either missing:

using UnityEngine;

using System.Collections;


public class yourFileName : MonoBehaviour {

at the beginning of your script. Most likely the latter.
