Unity System.String (Left & Right string) Bug

I'm tring to duplicate the script that this girl does to control the animation Mecanim 15:17 .And I get an error that says that the "e" and "q" buttons are not setup! Thank you so much for the effort that you've put to help me! I wish you a grate day!

<<< Script >> using UnityEngine; using System.Collections;

public class CharacterMovementController : MonoBehaviour {

 private Animator myAnimator;

 // Use this for initialization
 void Start () {

     myAnimator = GetComponent<Animator>();

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

     myAnimator.SetFloat("VSpeed", Input.GetAxis("Vertical"));
     if (Input.GetButtonDown("Jump"))
     {
         myAnimator.SetBool("jumping", true);
         Invoke("StopJumping", 0.1f);
     }
     if (Input.GetButtonDown("q"))
     {
         if((Input.GetAxis("Vertical") == 0f) && (Input.GetAxis("Horizontal") == 0f))
         {
             myAnimator.SetBool("TurningLeft", true);
         }else
         {
             myAnimator.SetBool("TurningLeft", false);
         }
     }
     if (Input.GetButtonDown("e"))
     {
         if ((Input.GetAxis("Vertical") == 0f) && (Input.GetAxis("Horizontal") == 0f))
         {
             myAnimator.SetBool("TurningRight", true);
         }
         else
         {
             myAnimator.SetBool("TurningRight", false);
         }
     }
     
 }
 void StopJumping()
 {
     myAnimator.SetBool("jumping", false);
 }
