Step 2 won't pass, Any suggestions would be awesome!

STEP 2 - 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 nums = int.Parse(Console.ReadLine());
            int tums = 0;
            int total = tums + nums;
            try
            {
              while (total > 0)
              {
                  Console.Write("yay");
                  total --;

              }

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

          } 


        }
    }
}

For the "try" to be effective, the "int.Parse" must be done inside its code block.

And I'm just curious ... what does "tums" represent?
