Not sure how to make this compile

Need to make this compile, but there is an error related to variable scope. Where can I move the declaration of input?

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(output);
        }
    }
}

Hi there! Well, let's start with the first problem you're having: the declaration of the input variable. There is something incorrect about that declaration. There's no data type.

Once you fix that, you'll see that there are other errors regarding the output variable. Might I suggest changing the name of that variable to something else and making a declaration of it where your input is but set to an empty string? :smiley:

I hope these hints will help, but let me know if you're still stuck! :sparkles:

I was stuck at this, but I did what you said about the input type for the output, I just put the Console.WriteLine(output); inside of the if/else statements

didnt make a declaration of the variable...and it worked

am I wrong?
