Why do input and output not exist?

No sure why input and output do not exist in this block of code, they are all in the static void section.

Program.cs 
using System;

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

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

            Console.WriteLine(output);
        }
    }
}

This challenge is mostly about correcting errors in scope. Some things to watch for:

  • Variables used in more than one scope must be declared in the outermost scope.
  • Variables can only be declared once.
  • Variables must be declared before they are used.
  • Remember that a new scope is created whenever you see an open brace ({)

Hopefully you can fix the code errors with these hints and pass the challenge.
