I don't understand where to insert the try catch.

I re watched the video and thought I should enter it Try and catch near the top but the compiler threw more errors. I put it this way not to change the scope like the question says. Anyone have any suggestions?

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        { 
            try{
                int input = int.Parse(entry);
            }
            catch (FormatException){
                 input = Console.ReadLine();
            }


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

            Console.WriteLine(output);
        }
    }
}

I'm not sure where you got the idea that you should add a "try...catch", or for that matter, any additional functional code to the original. You're only supposed to fix variable scopes so that the code compiles correctly.

The instructions say specifically, "Be sure to not change the intent or intended behavior of the code."

You don't need an input validation(try/catch). Just declare the input and output variables as a string.
