When I select the incorrect answer the next question loads with the the answer already displayed : I am completely new to coding and c#. I am studying a level 3 ICT and in my programming subject we are asked to make a quiz for essential skills students(Using forms.). 
I have been asked to create a very basic login in screen, topic selection screen, level selection screen and the actual questions and answers; answers are buttons. 

My issue is when I select the incorrect answer the next question loads but displays the correct answer for that question. 

Not quite sure what I need to do. I wanted to get this fixed over the weekend so I am unable to ask my teacher. 

The must remain very basic. 

Here is my code. I appreciate any help on this topic, Thanks.

```
here is my globals class:


```
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace EssentialSkills
{
    public static class Globals
    {
        public static string username, password;

        public static string user1, user2, user3, user4, user5, user6, loggedUser, admin;
        public static string pass1, pass2, pass3, pass4, pass5, pass6, adminPass1;

        public static List<string> listQuestionsNum0 = new List<string>();
        public static List<double> listAnswersNum0 = new List<double>();

        public static int intQuestionNumber = 0;

        public static int listIndex;

        public static int s;
    }
}
```
Many thanks.
