Quit Menu errors

Questions & Answers
1

I have a quit menu script, it works fine, but brings an error up in the unity editor.

    private var quitMenu;

    function Update () {

    if (Input.GetKeyDown (KeyCode.Escape)) { 
        if (quitMenu == true) { 

        quitMenu = false; 

        }
        else { 
        quitMenu=true; 

        }
        Time.timeScale = 0; 
       }

}

function OnGUI () {
if (quitMenu == true)
{

    GUI.BeginGroup (Rect (Screen.width / 2 - 50, Screen.height / 2 - 50, 200, 200));

    GUI.Box (Rect (0,0,100,170), "Game Paused");
    if (GUI.Button (Rect (10,30,80,30), "Resume")) {
    quitMenu = false;
    Time.timeScale = 1;
    }
    if (GUI.Button (Rect (10,80,80,30), "Restart")) {
    quitMenu = false;
    Time.timeScale = 1;
    Application.LoadLevel(0);
    }
    if (GUI.Button (Rect (10,130,80,30), "Quit")) {
         Application.Quit();
    }
}

    GUI.EndGroup ();
}

The error I got was

InvalidOperationException: Operation is not valid due to the current state of the object System.Collections.Stack.Peek () UnityEngine.GUIClip.Pop () UnityEngine.GUI.EndGroup () Quit Menu.OnGUI () (at Assets\Scripts\Quit Menu.js:43) UnityEditor.EditorGUIUtility:RenderGameViewCameras(Rect, Rect, Boolean, Boolean) UnityEditor.EditorGUIUtility:RenderGameViewCameras(Rect, Rect, Boolean, Boolean) UnityEditor.GameView:OnGUI() System.Reflection.MonoMethod:InternalInvoke(Object, Object[]) System.Reflection.MonoMethod:InternalInvoke(Object, Object[]) System.Reflection.MonoMethod:Invoke(Object, BindingFlags, Binder, Object[], CultureInfo) System.Reflection.MethodBase:Invoke(Object, Object[]) UnityEditor.HostView:Invoke(String) UnityEditor.DockArea:OnGUI()

Put the GUI.EndGroup() line in with the rest of the code. Otherwise you have a mismatched group (end without begin).

I have not looked at you script, nor do I know what you want to do, but if it is just to quit you can use my script.

And be sure to click the Quit button in the Inspector!

-Note: I have not edited my script, so it may want you to add some pictures/text.

var levelToLoad : String;
var normalTexture : Texture2D;
var rollOverTexture : Texture2D;
var beep : AudioClip;
var QuitButton : boolean = false;

function OnMouseEnter(){
    guiTexture.texture = rollOverTexture;
}
function OnMouseExit(){
    guiTexture.texture = normalTexture; 
}

function OnMouseUp(){
    audio.PlayOneShot(beep);
    yield new WaitForSeconds(0.35);

    if(QuitButton){
        Application.Quit();
        Debug.Log("This part works!");
    }
    else{
        Application.LoadLevel(levelToLoad); 
    }
}
