Really frustrated with this challenge..

Add input validation to your program by printing “You must enter a whole number.” if the user enters a decimal or something that isn’t a number. Hint: Catch the FormatException.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
           Console.Write("Enter the number of times to print \"Yay!\": ");
           var response = Console.ReadLine();
           int count = Int32.Parse(response);
           for(int i = 0; i < count; i++)
            {
             Console.WriteLine("Yay");   
            } if () 
            {
             Console.WriteLine("You must enter a whole number.");
            }
        }
    }
}

The instructions say "Hint: Catch the FormatException". If you're going to take that hint, you won't need an "if", but you will need a "try" and a "catch". Do you need to review the video about using those?
