Getting the "bummer! Try again!" error with no specification to what im doing wrong nor any console errors

No idea what i'm doing wrong, from what i can tell, the code does what it's supposed to do.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            var total = 0;

            while(true)
            {
                try
                {
                    Console.Write("Enter the number of times to print \"Yay!\": ");
                    int input = Convert.ToInt32(Console.ReadLine());

                    total = input + total;

                    while(total > 0)
                    {
                        Console.Write("Yay!");
                        total = total - 1;
                    }
                }
                catch(FormatException)
                {
                    Console.WriteLine("that is not a valid input, please try again");
                    continue;
                }
            }


        }
    }
}

I changed your code a bit and it worked fine. I just deleted the first while loop and the continue. Remember to print out “You must enter a whole number.” in your first catch clause.

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            var total = 0;
                try
                {
                    Console.Write("Enter the number of times to print \"Yay!\": ");
                    int input = Convert.ToInt32(Console.ReadLine());

                    total = input + total;

                    while(total > 0)
                    {
                        Console.Write("Yay!");
                        total = total - 1;
                    }
                }
                catch(FormatException)
                {
                    Console.WriteLine("You must enter a whole number.");

                }

        }
    }
}

but won't this make it so the code stops after the catch writeline? from what i can tell if some one types anything that can trigger an formatexception it'll say "You must enter a whole number." and then stop right? don't i have to make the code reset through a loop?

also, im getting the exact same thing on the challenge after that one

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            var total = 0;
                while(true)
                {
                    try
                    {
                        Console.Write("Enter the number of times to print \"Yay!\": ");
                        int input = Convert.ToInt32(Console.ReadLine());

                        if(input < 0)
                        {
                            Console.WriteLine("You must enter a positive number.");
                            continue;
                        }
                        else
                        {
                            total = input + total;

                            while(total > 0)
                            {
                                Console.Write("Yay!");
                                total = total - 1;
                            }
                        }
                    }
                catch(FormatException)
                {
                    Console.WriteLine("You must enter a whole number.");
                }
                }

        }
    }
}
