Need correct answer to this challenge.

Having trouble to add test logic in this challenge. I strongly suggest Treehouse to include sample answer to the challenges.

Program.cs 
int value = int.Parse(Console.ReadLine());

if (value < 0 || value > 20)
{
    throw new System.Exception();
}

try
{
    Console.WriteLine(string.Format("You entered {0}",value));
}
catch(Exception)
{
    Console.WriteLine("Value is out of bounds!");
}

You're very close.

The challenge says, "Now wrap the testing logic with a try/catch ..." What they mean by testing logic is where the value is tested and an exception is thrown.

Just move the beginning of your try block up a bit to cover that part of the code and you should pass.

This is now making a lot of sense to me. Thank you for your help!
