CS1061 Error in console

Hi, I'm getting errors in unity with
error CS1061: 'DialogueReader' does not contain a definition for 'playerInRange' and no accessible extension method 'playerInRange' accepting a first argument of type 'DialogueReader' could be found

playerInRange has the red squiggly line under it.

I'm quite new to coding so it's pretty confusing.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class DetectPlayer : MonoBehaviour
6. {
7.     public GameObject pressEtoTalkUI;
8.     public DialogueReader reader;
9.  
10.     bool playerInField = false;
11.  
12.     private void Update()
13.     {
14.         if (!playerInField)
15.             return;
16.  
17.         if (!reader.playerInRange)
18.             pressEtoTalkUI.SetActive(true);
19.         else
20.             pressEtoTalkUI.SetActive(false);
21.  
22.         if (Input.GetKeyDown(KeyCode.E))
23.         {
24.             reader.playerInRange = true;
25.         }
26.     }
27.  
28.     private void OnTriggerEnter(Collider other)
29.     {
30.         if (other.CompareTag("Player"))
31.         {
32.             playerInField = true;
33.         }
34.     }
35.  
36.     private void OnTriggerExit(Collider other)
37.     {
38.         if (other.CompareTag("Player"))
39.         {
40.             playerInField = false;
41.             reader.playerInRange = false;
42.         }
43.     }
44. }

 

Nevermind, it seems like i didn't reference it in another script
