UIToggle = null???? (Solved)

[Mr_Love_Gloves]

With my code I am trying to have a toggle button that mutes and plays sound, it works when it first loads up, but when I carry on through the game and end back at this start screen Toggle is = Null and the toggle does not mute the audio or work. I have no idea why its = null the second time round. Any help would be great 

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class SoundButtionGUI : MonoBehaviour {
5.        
6.  
7.         public UIToggle toggle;
8.        
9.  
10.         void Awake () {
11.                 if (PlayerPrefs.GetInt ("SoundMute") == 1) {
12.                         toggle.value = true;
13.                 } else {
14.                         toggle.value = false;
15.                 }      
16.  
17.         }
18.  
19.         void Update () {       
20.                 if (Application.loadedLevel == 0) {
21.                         if(toggle == null){
22.                                 Debug.Log ("Toggle = Null");
23.                         }
24.  
25.                                 if(toggle.value == true && toggle != null){
26.                                 PlayerPrefs.SetInt("SoundMute", 1);
27.                                 Invoke("audioOff", 0.01f);
28.                         } else{
29.                                 Invoke("audioOn", 0.01f);
30.                                 PlayerPrefs.SetInt("SoundMute", 0);
31.                         }
32.                 }
33.         }
34.  
35.         void audioOn(){
36.                 audio.volume = 1;
37.         }
38.        
39.         void audioOff(){
40.                 audio.volume = 0;
41.         }
42. }
43.

Never do anything in Awake() that involves other components.

Awake() is only for local value initialization. Rename it to Start().

Thank you that advice will help me, turns out the problem was every time the scene reloaded the toggle component disapeared from the variable so i just moved the script to the actual toggle and now everything works
