So for some reason the system exception messages from the example are not displaying as I work through the program. Here is my code. How do I fix it?

    class Program
    {
        static void Main(string[] args)
        {
            double balance = 0;
            double amount = 0;
            bool repeat=true;
            Console.WriteLine("Your Name - Week 4 PA Account Balance Calculations");
            Console.WriteLine();
            Console.Write("Please enter the starting balance: ");
            Double.TryParse(Console.ReadLine(), out balance);    

            while (repeat)
            {
                try
                {
                    Console.Write("\nPlease enter a credit or debit amount(0 to quit): ");
                    if (!Double.TryParse(Console.ReadLine(), out amount))
                        throw new FormatException();
                    else if (amount == 0)
                        repeat = false;
                    else if (balance + amount < 0)
                        throw new ArithmeticException();                    
                    else
                    {
                        balance = balance + amount;
                        Console.WriteLine("The updated balance is :{0}\n", balance.ToString("C2"));
                    }
                }
               
                catch (FormatException exp)
                {                  
                    Console.WriteLine("Input string was not in a correct format.");
                }
               
                catch (ArithmeticException  exp)
                {
                    Console.WriteLine("Amount entered cause account to be negative");                    
                }
               
                catch (Exception exp)
                {                    
                    Console.WriteLine(exp.Message);
                }
            }
           
            Console.WriteLine("The updated balance is :{0}\n", balance.ToString("C2"));
            Console.ReadLine();
        }
    }
