Buttons not working properly.

i am working on a 2d project and want to make it for mobile but for some reason my code on my MoveRight button works fine but my MoveLeft button doesn't.

Playercontroller script:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 using UnityEngine.EventSystems;
 using UnityStandardAssets.CrossPlatformInput;
 
 public class playercontroller : MonoBehaviour {
     public float speedForce= 50f;
     public Vector2 jumpVector;
     public bool isGrounded;
     public bool canMove;
     float speed;
     public Transform grounder;
     public float radiuss;
     public LayerMask ground;
     Animator anim;
 
     // Use this for initialization
     void Start () {
         canMove = true;
         anim = GetComponent<Animator> ();
     }
 
 
 
     // Update is called once per frame
     void FixedUpdate () {
         
 
         isGrounded = Physics2D.OverlapCircle (grounder.transform.position, radiuss, ground);
 }
 
 
 
 
     public void PMoveLeft (){
             
             speed = isGrounded ? speedForce : speedForce * 0.7f;
             GetComponent<Rigidbody2D> ().velocity = new Vector2 (-speed, 0);
             transform.localScale = new Vector3 (-1, 1, 1);
             anim.SetInteger ("AnimationState", 1);
         }
     
 
 
     public void PMoveRight (){
 
             
             speed = isGrounded ? speedForce : speedForce * 0.7f;
             GetComponent<Rigidbody2D> ().velocity = new Vector2 (speed, 0);
             transform.localScale = new Vector3 (1, 1, 1);
             anim.SetInteger ("AnimationState", 1);
 
     }
 
 
     public void PJump(){
             GetComponent<Rigidbody2D>().AddForce (jumpVector, ForceMode2D.Force);
     }
 
 
     public void PNotMove(){
         GetComponent<Rigidbody2D> ().velocity = Vector2.zero;
         anim.SetInteger ("AnimationState", 0);
     }
 
 
     void OnDrawGizmos()
     {
         Gizmos.color = Color.white;
         Gizmos.DrawWireSphere (grounder.transform.position, radiuss);
 
     }
 
 
 
     void OnTriggerEnter2D(Collider2D other)
     {
         if (other.tag == "deadly") {
             Debug.Log("Dead!");
             Application.LoadLevel(0);
 
         }
 
 
     }
 
     void OnTriggerStay2D(Collider2D other)
     {
         if (other.tag == "deadly") {
             Debug.Log("Dead!");
             Application.LoadLevel(0);
 
         }
     }
 
 
     void OnCollisionEnter2D(Collision2D other) 
     {
         if (other.gameObject.tag == "deadly") {
             Debug.Log("Dead!");
             Application.LoadLevel(0);
 
         }
     }
 
 
 
 }

MoveLeft script (attached to left button):

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.EventSystems;
 using UnityEngine.UI;
 
 public class MoveLeft : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
 {
     bool pointerDown = false;
     bool pointerUp = true;
     public GameObject Character;
 
 
     public void Start()
     {
         
     }
 
     public void OnPointerDown(PointerEventData eventData)
     {
         pointerDown = true;
         pointerUp = false;
     }
 
     public void OnPointerUp(PointerEventData eventData)
     {
         pointerDown = false;
         pointerUp = true;
 
     }
 
     void Update()
     {
         GameObject Character = GameObject.Find("Character");
         playercontroller PlayerController = Character.GetComponent<playercontroller>();
         if (pointerDown)
         {
 
             PlayerController.PMoveLeft ();
         }
 
         if (pointerUp) {
             PlayerController.PNotMove ();
         }
 
 
     }
 }

MoveRight Script(attached to right button):

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.EventSystems;
 using UnityEngine.UI;
 
 public class MoveRight : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
 {
     bool pointerDown = false;
     bool pointerUp = true;
     public GameObject Character;
 
 
     public void Start()
     {
         
     }
 
     public void OnPointerDown(PointerEventData eventData)
     {
         pointerDown = true;
         pointerUp = false;
     }
 
     public void OnPointerUp(PointerEventData eventData)
     {
         pointerDown = false;
         pointerUp = true;
 
     }
 
     void Update()
     {
         GameObject Character = GameObject.Find("Character");
         playercontroller PlayerController = Character.GetComponent<playercontroller>();
         if (pointerDown)
         {
             
             PlayerController.PMoveRight ();
         }
 
         if (pointerUp) {
             PlayerController.PNotMove ();
         }
 
 
     }
 }
 
 
 Help would be appreciated.
