How do you subtract 1 from the total number of "Yay!!"s before the program loops again?

I've created a loop for the program to display "Yay!". But I can't figure out how to let the program know to subtract 1 from the entry before it loops itself.

Program.cs 
using System;

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

            bool keepGoing = true;

            while(keepGoing)
            {
                Console.Write("Enter the number of times to print \"Yay!\": ");
                string entry = Console.ReadLine();
                double number = double.Parse(entry);


                if(number <1)
                {
                    keepGoing == false;
                }

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

Your subtraction is good.

But it is a problem if the loop includes the code that prompts the user and then takes in the input and converts it. All of that should happen only one time, before the loop starts.

Also, when you set keepGoing to false, you need to use an assignment operator ("=") instead of a comparison operator ("==").
