Scoping Assistance Is Needed

Attempted different ways to change the scoping but ran into various issues. Do not see the error. Thanks for any assistance.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
             string output = "";
        static void Main()
        {           
            string input = Console.ReadLine();  

               if (input == "quit")
            {
                string output = "Goodbye.";
            }
            else
            {
                string output = "You entered " + input + ".";
            }

            Console.WriteLine(output);
        }
    }
}

:point_right: Maybe a few hints will help:

  • declaring output outside of the conditionals was a good idea. But it should still be inside the method.
  • remember that you can assign something multiple times, but you can only declare it once.
  • declare something in two scopes, the inner one will "hide" the outer one.
