I cant deal with these errors >:[ any help on this one??

Error: NullReferenceException: Object reference not set to an instance of an object SoundButtionGUI.Update () (at Assets/SoundButtionGUI.cs:27)

Im getting the errors with : if(toggle.value == true)
>> this is the variable: public UIToggle toggle;

1. if (Application.loadedLevel == 0) {
2.             if(toggle.value == true){
3.                 PlayerPrefs.SetInt("SoundMute", 1);
4.                 Invoke("audioOff", 0.01f);
5.             } else{
6.                 Invoke("audioOn", 0.01f);
7.                 PlayerPrefs.SetInt("SoundMute", 0);
8.             }
9.         }

Ive tried this:
if(toggle.value == true && toggle != null && toggle.value != null && toggle.value != false)
Also: if(toggle == true) which stops the error but the code does not work because toggle sometimes returns null
Any help would be great


Any help would be great, I have had loads of these errors and have had to ask on here for every single one -_-

Im getting the errors with : if(toggle.value == true)

Obvious reason? 'toggle' is null.

Thanks for the quick reply, I found that out I just dont know what would be a fix to that? any ideas?

if(toggle != null && toggle.value == true )
I changed it to that which did stop the error, but now when i go through the levels and get back to the start screen the toggle button does not work as toggle is returning null

This is the code

1.         public Texture2D icon;
2.         public Texture2D iconClicked;
3.         public GUISkin toggleSkin;
4.        
5.         private bool muteToggle = false;
6.         private bool toggleImg = false;
7.         public UIToggle toggle;
8.        
9.         // Use this for initialization
10.         void Awake () {
11.                 if (PlayerPrefs.GetInt ("SoundMute") == 1) {
12.                         toggle.value = true;
13.                 } else {
14.                         toggle.value = false;
15.                 }
16.         }
17.         // Update is called once per frame
18.         void Update () {
19.                 if (Application.loadedLevel == 0) {
20.  
21.                                 if(toggle != null && toggle.value == true ){
22.                                 PlayerPrefs.SetInt("SoundMute", 1);
23.                                 Invoke("audioOff", 0.01f);
24.                         } else{
25.                                 Invoke("audioOn", 0.01f);
26.                                 PlayerPrefs.SetInt("SoundMute", 0);
27.                         }
28.                 }
29.         }
30.  
31.         void audioOn(){
32.                 audio.volume = 1;
33.         }
34.        
35.         void audioOff(){
36.                 audio.volume = 0;
37.         }

Never do anything in Awake() that involves other components. Do it in Start() instead. Awake() is like a constructor -- it should be used only for local variable initialization.
