Problem changing string value.

Hi, my game has a computer with a script attached to it. The script loads a mini-game, once the mini-game is complete (decided by an assistant script) it runs one of two functions, It will either open a door or change the direction of a conveyor belt. The direction of the Conveyor Belt is decided through a string variable: "Left" for left, or "Right" for right. Everything works in the computer script except changing the String value for the conveyor belt. I'm not getting any error messages. I ran some tests and determined that the part that doesn't work is the two if statements toggling the string.

Thanks in advance to whoever can help me!

The Computer Script (Changes the string):

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Computer : MonoBehaviour {
 
     public bool IsComplete;
     private bool PlayerInBox;
     public bool ChangesBelt;
     private bool HasChangedBelt;
     public bool OpensDoor;
     private bool HasOpenedDoor;
 
     public PlayerController Player;
     private ComputerAssistant Assistant;
     public ConvBelt Belt;
 
     public string Scene;
 
     public Animator Door;
 
     public bool Conv;
 
     void Start() {
 
         Player = FindObjectOfType<PlayerController>();
 
     }
 
     // Update is called once per frame
     void Update () {
 
         Assistant = FindObjectOfType<ComputerAssistant>();
 
         if (!IsComplete & PlayerInBox & Input.GetKeyUp(KeyCode.Return))
         {
             Application.LoadLevelAdditiveAsync(Scene);
             Player.IsCutscene = true;
         }
 
       if (Assistant.IsComplete)
       {
           IsComplete = true;
           Player.IsCutscene = false;
       }
 
         if (IsComplete == true)
         {
             if (OpensDoor & !HasOpenedDoor)
             {
                 Door.SetBool("Open", true);
                 HasOpenedDoor = true;
             }
 
             if (ChangesBelt == true & !HasChangedBelt == false)
             {
 
                 if (Belt.Direction == "Left")   //  <--------| 
                 {                                                               
                     Belt.Direction = "Right";                    
                     HasChangedBelt = true;                     // These don't work!
                 }                                                                
                                                                                  
                 if (Belt.Direction == "Right")  //    <-------|
                 {
                     Belt.Direction = "Left";
                     HasChangedBelt = true;
                 }
             }
 
         }
         
     }
 
     private void OnTriggerEnter2D(Collider2D collision)
     {
         if (collision.gameObject.name == "Player")
         {
             PlayerInBox = true;
         }
     }
 
     private void OnTriggerExit2D(Collider2D collision)
     {
         if (collision.gameObject.name == "Player")
         {
             PlayerInBox = false;
         }
     }
 }

The Assistant Script (Decides if the mini-game is complete):

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.SceneManagement;
 
 public class ComputerAssistant : MonoBehaviour {
 
     public bool IsComplete;
     public string Scene;
     
     // Update is called once per frame
     void Update () {
         if (IsComplete)
         {
             StartCoroutine(UnloadPuzzle());
         }
     }
 
     private IEnumerator UnloadPuzzle ()
     {
         yield return new WaitForSeconds(2);
         SceneManager.UnloadSceneAsync(Scene);
     }
 }

The Conveyor Belt Script (Has the string):

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class ConvBelt : MonoBehaviour {
 
     public string Direction;
 
     public GameObject Player;
 
     private bool PlayerInBox;
 
     // Use this for initialization
     void Start () {
         Player = FindObjectOfType<PlayerController>().gameObject;
     }
     
     // Update is called once per frame
     void Update () {
 
         if (PlayerInBox == true)
         {
             if (Direction == "Left")
             {
                 Player.transform.Translate(-0.1f, 0, 0);
             }
 
             if (Direction == "Right")
             {
                 Player.transform.Translate(0.1f, 0, 0);
             }
         }
         
     }
 
     private void OnTriggerEnter2D(Collider2D collision)
     {
         if (collision.gameObject.name == "Player")
         {
             PlayerInBox = true;
         }
     }
 
     private void OnTriggerExit2D(Collider2D collision)
     {
         if (collision.gameObject.name == "Player")
         {
             PlayerInBox = false;
         }
     }
 }
