Code not working for the quiz

Any ideas why?, I know that the ArguementNullExcpetion isn't required but I just wanted to eliminate all possibilities

Program.cs
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            bool state = true;

            while (state)
            {
                Console.Write("Enter the number of times to print \"Yay!\": ");

                // Get user input
                string userInput = Console.ReadLine();
                int currentNumber = 0;

                try
                {
                    var counter = int.Parse(userInput);

                    if(counter <= 0)
                    {
                        Console.WriteLine("You must enter a whole number.");
                        continue;
                    }


                    while (currentNumber < counter)
                    {
                        Console.WriteLine("Yay!");
                        currentNumber += 1;

                        if (currentNumber == counter)
                        {
                            state = false;
                            break;
                        }
                    }

                }

You have an outer loop that prevents the program from ending when invalid input is entered. 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.
