Program.cs 
using System;

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

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

input has not been declared anyway, and you declare a variable like this: *string name = * or *int age = *.

output is being declared twice but inside curly-braces ({ }) and that prevent the program from reading that variable outside the curly-braces, so you should declare it somewhere outside the curly-braces.

I would advice you to re-watch the video(s) about this subject again :-)

using System;

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

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

            Console.WriteLine(output);
        }
    }
}
