What am I missing?

Program.cs 
using System;

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

            string input = Console.ReadLine();
            try
            {

            if (input == "quit")
            {
                string output = "Goodbye.";
            }
            else
            {
                string output = "You entered " + input + ".";
            }
            }
            catch(FormatException)
            {
            Console.WriteLine("That is not a valid input");
            continue;
            }
            Console.WriteLine(output);
        }
    }
}

That's the code that worked for me. 

using System;

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

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

            Console.WriteLine(output);
        }
    }
}
