Stuck on Yay!

I'm not quite sure what the code is actually error'ing out at. Something about Null. I added code to cover a zero (0) or less, NULL (At least I think that I did), and non-number input.

I think that I am close.

Thanks,

Rob

Program.cs 
using System;

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

            try
             {
              var totalTimes = int.Parse(times);  

               if (totalTimes <= 0)
               {
                Console.WriteLine(totalTimes + " is not an acceptable value.");
                continue;
               }

               while (totalTimes > 0)
               {
                Console.WriteLine("\"Yay!\" ");
                 totalTimes --;
               }
             }
             catch(FormatException)
              {
                Console.WriteLine("That is not valid input.");
                continue;
              }

            }


        }
    }
}

You have an outer loop that prevents the program from ending.

A program built according to the instructions will prompt and accept input one time, and based on the input it will either print "Yay!"s or an error mesage. Either way, it should end. With the extra loop it never ends.

Also, zero might need to be allowed as a value (in which case the program would just end).
