Hi Jeremy,

Can you post the entirety of this script? That will help a lot!

public class PlayerMovement : MonoBehaviour {

private Animator playerAnimator;
private float moveHorizontal;
private float moveVertical;
private Vector3 movement;
private float turningSpeed = 20f;
private Rigidbody playerRigidbody;

// Use this for initialization
void Start () {

    // Gather componets from the Player Gameobject
    playerAnimator = GetComponet<Animator> (); 
    Rigidbody = Getcomponet<Rigidbody> (); 


// Update is called once per frame
void Update () {

    // Gather input from the keyboard
    moveHorizontal = input.GetAxisRaw ("Horizontal"); 
    moveVertical = input.GetAxisRaw ("Vertical");

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


void FixedUpdate () { 

    // If the players movement Vector doesn't equal zero...
    if (movement != Vector3.Zero) {

        //...then create a target rotaion based on movement Vector...
        Quaternion targetRoation= Qauternion.LookRoatation(movement, Vector3.up);

        // and create another roatation that moves from the current rotation too the target rotation...
        Quaterion newRoataion = Quaternion.Lerp (playerRigidbody.rotation, targetRoataion, turningSeep * Time.deltiaTime)

        // and change the Player's rotation too the new incremental rotation...

        // then play jump animation
        playerAnimator.SetFloat ("Speed", 3f);
    } else {
        // Otherwise don't play jump animation
        playerAnimator.SetFloat ("Speed", 0f);

There's several places in your code where you don't have the proper words or the capitalization isn't correct. Make sure you're paying close attention to exactly what is written. I don't know personally if it will solve the issue but I do know that you will have issues the way things are.

The best way to do it is to pause on the video and read the code backwards. From the bottom to the top, right to left. This is one of the best ways to debug your code because your brain will start autocompleting things in your head and make things look correct when going the right way, but going backwards you have to pay closer attention thus you don't have that issue.
