It says "unexpected word catch in code" am I using catch wrong?

just at a lost i looked it up online and i seem to have it all correct maybe someone can spot what I am missing

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");

            var entry = int.Parse(Console.ReadLine());
              for(var i = 0; i < entry; i += 1)
            {
                Console.WriteLine("Yay!");
            }

        }            
    }
     catch(FormatException)
     {                  Console.WriteLine("You must enter a whole number.");
                        continue;
     }
}

Hello Jonathan,

This step of the challenge wants you to catch the scenario where a user inputs data we don't expect in the console. This means you'll want to try...catch Console.ReadLine to make sure the input is valid.

First you'll need to make sure your entry variable is at a higher scope so it can be accessible via the try catch as well as the for loop.

...
Console.Write("Enter the number of times to print \"Yay!\": ");
var entry = 0;
...

Then place the Console.ReadLine call in a try block

 try 
 {
     entry = int.Parse(Console.ReadLine());
 }

Now you can move your catch block immediately following the try block.

I hope this helps.

Happy Coding :)
