On the third step of c#basics it throws error " It looks like Task 1 is no longer pass" But I can't find the reason

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {


       while(true)
       {
            Console.Write("Enter the number of times to print \"Yay!\": ");
             string entry = Console.ReadLine();
           if(int.Parse(entry)<=0)
                        {
                             Console.WriteLine("You must enter a positive number.");
                             continue;
                         }
            try
            {
                   int num = int.Parse(entry);
                   int count = 0;

                     while(count < num)
                        {                         
                         Console.WriteLine("Yay!");
                         count++;
                        }

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

        }
    }
}
