No enclosing loop ¿? What is wrong?

Program.cs 
using System;

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

            var counter = 0;

            Console.Write("Enter the number of times to print \"Yay!\": ");
            var input = Console.ReadLine();

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

                while (counter < times)
                {
                    Console.Write("Yay!");
                    counter += 1;
                }

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

            }
            catch (ArgumentNullException)
            {
                Console.WriteLine("You must enter a positive number");
                continue;
            }    

            Console.ReadLine();
        }   
    }
}

You are close but you need to change your check for negative numbers to something like this:

using System;

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

            var counter = 0;

            Console.Write("Enter the number of times to print \"Yay!\": ");
            var input = Console.ReadLine();

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

                if(times < 0){
                    Console.WriteLine("You must enter a positive number");
                } else {

                    while (counter < times)
                    {   
                        Console.Write("Yay!");
                        counter += 1;
                    }  
                }

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

            }

            Console.ReadLine();
        }   
    }
}
