Not quite sure what I'm doing wrong

I declared input as a string variable and then declared the output variable in the main method but I don't understand why it is coming up as incorrect

Program.cs
using System;

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

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

            Console.WriteLine(output);
        }
    }
}

A variable should only be declared once. It can be assigned many times, but in a plain assignment the name will not be preceded by the type.

Since you've declared "output" in Main and made it a string, you don't need to use "string" before the variable name in the if and else blocks. It thinks you're trying to declare a new variable called output in each of those lines but it already exists.
