Show score on gameover screen?

Hello Unity Answers,

I'm trying to make a simple gameover screen with the score shown to the player.

I have created a new scene and copied everything from the main scene into it and repositioned the score text but the score doesn't update.

All ideas & suggestions welcome.

 using System;
 using System.Collections.Generic;
 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class Question10 : MonoBehaviour {
     
     private Rect windowRect = new Rect (500, 100, 400, 200); //Window size
     public bool question10;
     private int count;
     public Text countText;
 
     private bool showTimer = true;
     private float Timer = 10f;
 
     void start()
     {
         count = 0;
         SetCountText ();
     }
 
     void FixedUpdate(){
         if (showTimer == true) {
             Timer -= Time.deltaTime;
         }
         
         if (Timer <= 0f) {
             showTimer = false;
             Timer = 10f;
             Destroy (this.gameObject);
             Application.LoadLevel (Application.loadedLevel);
         }
     }
     
     void OnGUI()
     {
         windowRect = GUI.Window (0, windowRect, WindowFunction, "Ebola Quiz Island"); //window on screen
     }
     
     
     void WindowFunction (int windowID) 
     {
         // Draw any Controls inside the window here
         GUI.Label(new Rect (30, 25, 400, 50), " How many proven treatments are there for Ebola?"); // Question
         
         if (GUI.Button (new Rect (20, 100, 100, 30), "None")) 
         {
             Destroy (this.gameObject);
             count = count + 10;
             SetCountText ();
             Application.LoadLevel("Gameover");
         }
 
         if (GUI.Button (new Rect (280, 100, 100, 30), "One"))
         {
             Destroy (this.gameObject);
             Application.LoadLevel("Gameover");
         }
 
         if (GUI.Button (new Rect (20, 150, 100, 30), "Two"))
         {
             Destroy (this.gameObject);
             Application.LoadLevel("Gameover");
         }
 
         if (GUI.Button (new Rect (280, 150, 100, 30), "Three"))
         {
             Destroy (this.gameObject);
             Application.LoadLevel("Gameover");
         }
 
         if (showTimer == true) 
         {
             GUI.Label (new Rect (175, 50, 200, 50), "Timer: " + Timer.ToString ("F0"));
         }
 
 
     }
 
         void SetCountText()
         {
             ValuesHolder.answersCount++;
             countText.text = "Score: " + ValuesHolder.answersCount.ToString();
         }
     
 }
 

 using UnityEngine;
 using System.Collections;
 
 internal class ValuesHolder
 {
     internal static int answersCount = 0;
 }
 

When the player clicks the None the scoreboard scene ( Application.LoadLevel("Gameover");) will be loaded but the score won't be updated? :(
