Variable Scope Code Challenge

Question

Not sure what if Im solving it right. I do keep getting an error about the catch whenever I put anything in there.

Program.cs

using System;

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

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

There are a few problems:

First, you don't need the "()" after catch, just the word catch by itself

try 
{ 
    // do something
}
catch
{
    // do something (or nothing!)
}

(Note, the parentheses are used if catching something specific like catch (System.Exception) {}

But you'll still have some other problems:

You never initialized input (you need: var input = Console.ReadLine())
Because of above, when the code got to this line of the try block, it will fail and go to catch
You can't use output after the try/catch block, because it won't be defined if try fails (i.e. move Console.WriteLine(output) to the inside of the try block)

Try again with that info. I don't want to give you the full answer if that will get you what you need. Comment back if you need any more help!
