I'm on the last task and I can't seem to get the validation sequence correct. Help will be really appreciated.

What am I missing here? I tried to define the negative number validation question the problem asks and nothing seems to work. I am really having a hard time with this last question.

Program.cs 
using System;

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

          var numOfTimes = System.Console.ReadLine();



          try
          {

          int num = int.Parse(numOfTimes);

          for (int i=0; i<num; i++) {

          System.Console.WriteLine("\"Yay!\"");
          }

          }
          catch (FormatException)
          {

           System.Console.WriteLine("You must enter a whole number.");

          }
        }
    }
}
