This is going to be easiest to help you with if we can see the code. At the bottom of the "Add an Answer" section is a link to a Markdown Cheatsheet where you will find instructions on how to post your code. My guess is that something is not correct in the PlayerMovement.cs file.

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 compoents from the player gomeObject
    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 the player movement vector does not equal zero...

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

    //...and create another rotation that moves from the current rotation to the target rotation...
    Quaternion newRotation = Quaternion.Lerp(playerRigidbody.rotation, targetRotation, turningSpeed * Time.deltaTime);
    //...and change the players rotation to the new incremetial rotation...
    playerRigidbody.MoveRotation(newRotation);

    if (movement != Vector3.zero) {
        //... then play jump animation.
        playerAnimator.SetFloat ("Speed", 3f);
    } else {
        //otherwise,don't play jump animation.
        playerAnimator.SetFloat ("Speed", 0f);
    }
}

}
