Hi there! Cindy Lea has a correct solution for you here. I'm just going to add a brief explanation :smiley:

using System;

namespace Treehouse.CodeChallenges { 
  class Program { 
    static void Main() {
        string input = Console.ReadLine();   //we need to say what type this variable is otherwise it's not "declared"
        string output;  //again we need a declared variable for output so we can use it later

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

        Console.WriteLine(output);
    }
  }
}

Happy coding! :thumbsup:
