Public Scene Variables not appearing in the inspector

I am aware that this question has been asked before but I have searched for the answer and none of the proposed solutions have worked for me. I have checked both of the scripts in my project currently for errors and have found none. My variable is public.

Script the variable is in:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.SceneManagement;
 
 public class doorEnterController : MonoBehaviour {
 
     public Scene toLoad;
 
     // Use this for initialization
     void Start () {
         
     }
     
     // Update is called once per frame
     void Update () {
         
     }
 }

The other script in my project:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class playerController : MonoBehaviour {
 
 
     // Use this for initialization
     void Start () {
 
     }
     
     // Update is called once per frame
     void Update () {
         
     }
 
     void FixedUpdate()
     {
         if (Input.GetKey(KeyCode.W))
         {
             gameObject.transform.Translate(new Vector3(0, 0.1f, 0));
         }
         if (Input.GetKey(KeyCode.S))
         {
             gameObject.transform.Translate(new Vector3(0, -0.1f, 0));
         }
         if (Input.GetKey(KeyCode.A))
         {
             gameObject.transform.Translate(new Vector3(-0.1f, 0, 0));
         }
         if (Input.GetKey(KeyCode.D))
         {
             gameObject.transform.Translate(new Vector3(0.1f, 0, 0));
         }
 
     }
 }
