frog will not move correctly

from keeps going back in default position and with move only when i move it certain ways. using UnityEngine; using System.Collections;

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 the componets from player Gameobject
    playerAnimator = GetComponent<Animator> (); 
    playerRigidbody = GetComponent<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 player movement vector does not equal zero play the jump animation otherwise do not

    // then create a target rotation based on movement vector.
    Quaternion targetRotation = Quaternion.LookRotation(movement, Vector3.up);

    // create another rotation that moves from the current rotation to the target rotation
    Quaternion newRotation = Quaternion.Lerp(playerRigidbody.rotation, targetRotation, turningSpeed * Time.deltaTime);
    // change players rotation to new incremental rotation
    playerRigidbody.MoveRotation(newRotation);
    if (movement != Vector3.zero){
        playerAnimator.SetFloat ("Speed", 3f);
}else{
        playerAnimator.SetFloat ("Speed", 0f);
    }
}

}

PlayerMovement at the top isn't capitalized, and you don't have; playerFootsteps.enabled = false;

Heres what its supposed to look like

using UnityEngine;
using System.Collections;

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 () {
        playerAnimator = GetComponent<Animator> ();

        playerRigidbody = GetComponent<Rigidbody> ();
    }

    // Update is called once per frame
    void Update () {
        moveHorizontal = Input.GetAxisRaw ("Horizontal");
        moveVertical = Input.GetAxisRaw ("Vertical");

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

    void FixedUpdate () {
        if (movement != Vector3.zero) {  

            Quaternion targetRotation = Quaternion.LookRotation(movement, Vector3.up);

            Quaternion newRotation = Quaternion.Lerp (playerRigidbody.rotation, targetRotation,turningSpeed * Time.deltaTime);

            playerRigidbody.MoveRotation(newRotation);
              playerAnimator.SetFloat ("Speed", 3f);

            playerFootsteps.enabled = true;



        } else {
            playerAnimator.SetFloat ("Speed", 0f);


            playerFootsteps.enabled = false;
        }
    }
}
