1,876 PointsFinal code challenge 3 of 3 - "I entered -1 but nothing is printing out" ?
I tried multiple ways, but it still is not working properly
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.");
}
}
}
}

231,269 PointsIt 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.

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.");
}
}
