Variable Scope Code Challenge

I am stuck on this code challenge and cant seem to figure out what it is wanting me to do. If I run the code as is I get "Program.cs(19,12): error CS1524: Unexpected symbol Console', expectingcatch' or `finally' Compilation failed: 1 error(s), 0 warnings" If anyone can help me understand this i would greatly appreciate it.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {            
            input = Console.ReadLine();
            try
            {
                if (input == "quit")
                {
                    string output = "Goodbye.";
                }
                else
                {
                    string output = "You entered " + input + ".";
                }
            }
            Console.WriteLine(output);
        }
    }
}

:point_right: When you add try, you also need to add catch.

For a "try" block to be effective, and to compile correctly, it would be followed by a "catch" block. But adding "try" and "catch" is not part of this challenge.

This challenge is about fixing errors in variable scope. Look for places where a variable is used in one scope but declared in another, or declared more than once.

Okay, do you have any idea which video I should watch to maybe get a better grasp on declare a variable?

You should put String type to variable "input" also.
