John Lemon on play- nothing moves

I too just finished tut, nicely done tho I knew a lot of it already but still some I did not, but after done with script in place. and I made sure my script matched and its perfect - JohnLemon just rotates in place,doesn't have forwards movement of any kind. No errors of any kind anywhere.

Using very latest unity through hub.
Btw while not a long time programmer, I grasp in its entirety everything that is going on so its not that. Here is the script as attacked at bottom, in Inspector for John Lemon ;

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. public class PlayerMovement : MonoBehaviour
6. {
7.     public float turnSpeed = 20f;
8.     Vector3 m_Movement;
9.     Quaternion m_Rotation = Quaternion.identity;
10.     Animator m_Animator;
11.     Rigidbody m_Rigidbody;
12.  
13.     void Start()
14.     {
15.         m_Animator = GetComponent<Animator>();
16.         m_Rigidbody = GetComponent<Rigidbody>();
17.     }
18.         void FixedUpdate()
19.     {
20.         float horizontal = Input.GetAxis("Horizontal");
21.         float vertical = Input.GetAxis("Vertical");
22.         m_Movement.Set(horizontal, 0f, vertical);
23.         m_Movement.Normalize();
24.         bool hasHorizontalInput = !Mathf.Approximately(horizontal, 0f);
25.         bool hasVerticalInput = !Mathf.Approximately(vertical, 0f);
26.         bool isWalking = hasHorizontalInput || hasVerticalInput;
27.         m_Animator.SetBool("IsWalking", IsWalking);
28.         Vector3 desiredForward = Vector3.RotateTowards(transform.forward, m_Movement, turnSpeed * Time.deltaTime, 0f);
29.         m_Rotation = Quaternion.LookRotation(desiredForward);
30.     }
31.      void OnAnimatorMove()
32.     {
33.         m_Rigidbody.MovePosition(m_Rigidbody.position + m_Movement * m_Animator.deltaPosition.magnitude);
34.         m_Rigidbody.MoveRotation(m_Rotation);
35.     }
36. }
37.  

Be easier if I had an error to share , but no. Any screenshots anyone needs I can happily share
