Help with Main Menu Buttons...

Hi There, I'm fairly new to C# programming in Unity and was wondering if anyone could help me out. I have written a Script of how to do a Start Button and Exit Button. (Simple really, I thought.) I since came across a few typo's but now it's all resolved. Or should be, My only problem is it doesn't work and the console shows, "Assets/MainMenu.cs(50,9): error CS8025: Parsing error". Visual Studio just shows the last line of my script highlighted with,

Severity Code Description Project File Line Suppression State Error CS1513 } expected SandBox Project.CSharp C:\Users\Faith\Desktop\Nathan\PROGRAMMING\Unity\SandBox Project\Assets\MainMenu.cs 50 Active

Here is my code:

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class NewBehaviourScript : MonoBehaviour
 {
 
     public Canvas quitMenu;
     public Button startText;
     public Button exitText;
     // Use this for initialization
     void Start()
     {
 
         quitMenu = quitMenu.GetComponent<Canvas>();
         startText = startText.GetComponent<Button>();
         exitText = exitText.GetComponent<Button>();
         quitMenu.enabled = true;
 
 
     }
 
 
     public void ExitPress()
 
     {
         quitMenu.enabled = true;
         startText.enabled = false;
         exitText.enabled = false;
     }
 
     public void NoPress()
 
     {
         quitMenu.enabled = false;
         startText.enabled = true;
         exitText.enabled = true;
 
     }
 
     public void StartLevel()
     {
         Application.LoadLevel("LevelLoadingScreen");
     }
 
        public void exitMenu()
         {
             if (Input.GetKey("escape"))
                 Application.Quit();
         }

Ps: Thanks in advance...
