Can't get roll a ball to roll

After taking a decade or so off from programming I am trying to restart using Unity... new to it and C# (used C a lot). When I hit play the ball does not move at all. I think I followed everything in the tutorial exactly, and have read all the questions like mine where the answer ends up being a typo. I am not seeing my mistake, here is the code:

using UnityEngine; using System.Collections;

public class PlayerController : MonoBehaviour { public float speed;

 void FixedUdate()
 {
     float moveHorizontal = Input.GetAxis ("Horizontal");
     float moveVeritcal = Input.GetAxis ("Vertical");

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

     Debug.Log ("moved " + moveHorizontal + " " + moveVeritcal);

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

}

FWIW I am REALLY impressed something like this is available for free!!!
