2D CrossPlatformInput - AxisTouchButtons are not working?

Okey , so I want to add buttons to my pc game. My character is working fine with keyboard. I watched couple of videos about adding buttons. Later I created 2 buttons for left and right and added "AxisTouchButton.cs" script (from Standard Assets - Cross Platform Inputs) to these buttons ,set to horizontal settings -1 for left and +1 for right button. I also edited movement script that attached to player. But nothings is happening. What am i doing wrong?

 //using System.Collections;
 //using System.Collections.Generic;
 //using UnityEngine;
 //using UnityStandardAssets.CrossPlatformInput; 
 
 
 public class move : MonoBehaviour
 {
     float horizontal;
     
     void Start()
     {
 
     }
     void Update()
     {
         horizontal = CrossPlatformInputManager.GetAxis("Horizontal");
         transform.Translate(Vector3.right * Time.deltaTime * 20.0f * horizontal);
     }
 
 }
