This works in workspace, if given any non-positive number it tells me to enter a positive and gives me another chance to do so. (I have also tried removing the = for <= so entering 0 would be fine just to see if that was the problem) I don't get what is wrong if the code works in workspace. Thanks
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
try
{
int count;
while(true)
{
Console.Write("Enter the number of times to print \"Yay!\": ");
string input = Console.ReadLine();
count = int.Parse(input);
if(count <= 0)
{
Console.WriteLine("You must enter a positive number.");
}
else
{
break;
}
}
int i = 0;
while(i < count)
{
i += 1;
Console.WriteLine("Yay!");
}
}
catch(FormatException)
{
Console.WriteLine("You must enter a whole number.");
}
}
}
}

A program that follows the challenge instructions will only ask for input one time, and either print "Yay!"s or an error message. But either way it should end.
