Where is the Scope.

I think I know what is wrong. This might have something to do with the scope but I'm not entirely sure.

Program.cs 
using System;

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

            if (input == "quit")
            {
                Console.WriteLine("goodbye.");

            }
            else
            {
                string output = "You entered " + input + ".";
            }

            Console.WriteLine(output);
        }
    }
}

Hey Aaron,

You are right when you say that the code is not compiling due to scope. Try and declare the variables outside of the If statement. Also remember to declare the type of the variable. Hope that helps!

Hi I think you forgot to declare your input variable, to do so either put var or string in front of the variable statement.
