C# Instance problem

Hello everyone in the community! i just would like to ask if theres a problem in instance accessing in c#. I have created several c# scripts: the first is the main where there is the oncollider script on it and some ongui functions which primary purpose is to make a quiz game.

The scripts are working great until i created 100's of it (one question = one script). So i arranged my scripts into folders(group by subject of quiz).

To make it work i drag 7 scripts into a box where they see each other, to make the instance thing work and it worked. But later on i decided to add a sound each time the player clicks on the correct answer and i don't want to hugely edit each script by adding variables and if statements for audio playing. So i decided create one c# script with a var of boolean value and if that boolean value is true it will play a sound.

The sound script to one of the boxes and edit the other quiz scripts and i added a line like this QuizeSound.Instance.Sounder=true; so everytime i clicked on the right answer in the quiz i will hear a sound. Working on the first box as i tested it i attached it to other quiz boxes so it will work too. Unfortunately after editing the scripts, it doesn't appear to read the variable of the sound script. I run the game and monitored the boolean variable in runtime and its always false like theres no connection at all even the script is attached and theres a QuizeSound.Instance.Sounder=true in each script.

Is this a bug or is this normal that you can only use instance in one object because when i created another sound script instance(just renamed the class and the instance) it worked.

To clarify it more it looks like this:

Box 1 scripts: quiz1, quiz2, quiz3, quiz4, quiz5, sounder Box2 2 sciprts: quiza, quiz2a, quiz3a, quiz4a, quiz5a, sounder

The box 1 works but the box 2 doesn't.

Then i do this:

Box 1 scripts: quiz1, quiz2, quiz3, quiz4, quiz5, sounder Box2 2 sciprts: quiza, quiz2a, quiz3a, quiz4a, quiz5a, sounder2

and it worked. I don't know whats wrong in solution 1 but theres no compiling error there.

using UnityEngine; using System.Collections;

public class QuizeSound : MonoBehaviour { public static QuizeSound Instance; public AudioClip impact;

 public bool Sounder =false;
 
 public int answered;
 
 void Start () 
 {
     
     Instance = this;
 }
 
 
     
 void Update () 
 {
     
 
     
   
     if (Sounder == true)
     {
         
             
     

      
         
         audio.PlayOneShot(impact);
         Sounder= false;
         
                                                     
         
         
         
         
 
 }

} }

Above is the sounder instance code and below is a quiz script sample that is accessing it: using UnityEngine; using System.Collections;

public class Quize73D2 : MonoBehaviour { public static Quize73D2 Instance;

 public int activeDistance = 10;

 public Transform Player;

public GUISkin customSkin; public static int answered = 0;

 void Start()
 {
     Instance = this;
 }

  void OnGUI () {
       GUI.skin = customSkin;
    if (Vector3.Distance(transform.position, Player.position) <= activeDistance)
    {
        GUI.Box(new Rect(350, 15, 800, 500), "What is the 3ds Max hotkey for rotate button?");
        
        
        
        // Make the first button. 
        if (GUI.Button(new Rect(500, 120, 500, 30), "R"))
        
        {
           

            QuizeController3D2.Instance.ShowQuize73D2 = false;
            QuizeController3D2.Instance.WonOrFailed3D2 = true;

        }
        
        // Make the second button.
        if (GUI.Button(new Rect(500, 200, 500, 30), "E"))
        
        {
             QuizeController3D2.Instance.answered++;QuizeSound.Instance.Sounder=true;
            QuizeController3D2.Instance.ShowQuize73D2 = false;
            QuizeController3D2.Instance.WonOrFailed3D2 = true;
            //One wrong answer  means fail and this is a wrong answer therefore display a "you are failed" message then exit
           
            
        }
        
        // Make the 3rd button.
        if (GUI.Button(new Rect(500, 280, 500, 30), "C"))
        {
            QuizeController3D2.Instance.ShowQuize73D2 = false;
            QuizeController3D2.Instance.WonOrFailed3D2 = true;
            //One wrong answer  means fail and this is a wrong answer therefore display a "you are failed" message then exit
        }
        
        
        
        // Make the 4th button.
        if (GUI.Button(new Rect(500, 360, 500, 30), "Alt + shift"))
        {
            QuizeController3D2.Instance.ShowQuize73D2 = false;
            QuizeController3D2.Instance.WonOrFailed3D2 = true;
            //One wrong answer  means fail and this is a wrong answer therefore display a "you are failed" message then exit
        }
        
        
        
        
        
        
        
    }
 }
