Final code challenge 3 of 3 - "I entered -1 but nothing is printing out" ?

I tried multiple ways, but it still is not working properly

Program.cs 
using System;

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

            Console.Write("Enter the number of times to print \"Yay!\": ");
            var entry = Console.ReadLine();
            try
            {
                var yayLimit = int.Parse(entry);
                if (yayRunningTotal <= -1)
                {
                    Console.WriteLine("You must enter a positive number.");
                }
                while (yayRunningTotal < yayLimit)
                {
                    yayRunningTotal += 1;
                    Console.WriteLine("Yay!");
                }
            }
            catch (FormatException)
            {
                Console.WriteLine("You must enter a whole number.");
            }
        }
    }
}

It looks like you're validating the wrong variable.

When you convert the input to a numeric value, you store it in the variable yayLimit. But when you perform a test for validity you check yayRunningTotal instead (which is still 0 at this point).

Also, check the instructions again but you might want your validity test to exclude 0 as well as negative values.

please check the comments

using System;

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

            Console.Write("Enter the number of times to print \"Yay!\": ");
            var entry = Console.ReadLine();
            try
            {
                var yayLimit = int.Parse(entry);
                if (yayRunningTotal <= -1)//why are you checking for yayRunningTotal, and the other why is it checking for less than -1
                {
                    Console.WriteLine("You must enter a positive number.");
                }
                while (yayRunningTotal < yayLimit)
                {
                    yayRunningTotal += 1;
                    Console.WriteLine("Yay!");
                }
            }
            catch (FormatException)
            {
                Console.WriteLine("You must enter a whole number.");
            }
        }
    }
