Please help with Challenge Task 1 of 3 in the C# basics course Final.

Below is my code and I'm not sure if I'm even close to getting this question correct but now I've thrown and exception. I'm not sure if the Int32.Parse is correct or how to get it to work properly. Please help explain what I'm doing wrong so I could possible see it on my end to correct the problem. Thanks!

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 (entry == "quit");
            {
                break;
            }

            try
            {
                int number = Int32.Parse(entry);

                if (number >= 0)
                {
                    Console.WriteLine( number + " is not an exceptable value.");
                    continue;
                }

                else if (number >= 1)
                {
                    Console.WriteLine("Yay!");
                }
            }

            catch(FormatException)
            {
                Console.WriteLine("This is not valid input.");
                continue;
            }

        }        
    }
}

}

This problem is a little simpler. the number should only be read in once, and used in the loop counter. The while(true) loop isn't necessary:

using System;

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

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

                string entry = Console.ReadLine();

                try {
                    int number = Convert.ToInt32(entry);

                    for(int i = 0; i < number; i++) {
                        Console.WriteLine("Yay!");
                    }
                } catch(FormatException) {
                    Console.WriteLine("This is not valid input.");
                }
        }
    }
}
