It's not working.

I tried to do as the video says and indent below the input variable, but it still says it couldn't be compiled.

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();
        }
    }
}

Cause you didn't define type of input variable, use string or var to declare like this string input = Console.ReadLine() and code will compile.

So you have multiple declaration of output, string output need to be declared before if else statement. And in Console.WriteLine() you need to pass output variable as an argument.
