Roll a Ball input problem Unity 4.6

Hi there!!
I was seeing the old series of tutorials for the Roll a Ball project, i have followed every step on the video and by what i can see everything is as it should be … everything appears to be fine, no errors at all… but i can’t Move the ball, i mean i press “W” or the “Up” arrow and doesn’t happen anything! It is like if there was no Input.
What’s going on?

Notice that i am using the 4.6 version

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour 
{

	public float speed;
	
	void FixedUpdated()
	{
		float moveHorizontal = Input.GetAxis("Horizontal");
		float moveVertical = Input.GetAxis("Vertical");

		Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

		rigidbody.AddForce(movement * speed * Time.deltaTime);
	}

}

Try naming the function FixedUpdate instead of FixedUpdated.
