The value entered will not be a bool, it will be a number of how many times to print.

But to add the error checking needed by the next task you will need to use a "try...catch" combination.

using System;

namespace Treehouse.CodeChallenges { class Program { static void Main() { Console.Write("Enter the number of times to print \"Yay!\": "); var y = Console.ReadLine();
try { var t = double.Parse(y); int z = 0; bool yes = true; while(yes) { Console.Write("Yay!"); z=z+1; if(t==z) { yes = false; } } Console.Write("Youve enetered " +t+" times"); } catch(FormatException) { Console.Write("You must enter awhoel number."); }

    }
}

}

It's difficult to read unformatted code, but at first glance it looks like you added an extra message to show the number of times entered (doing things not asked for can confused the validation system), and your error message needs to be spelled the same was as it was given in the instructions.

And when posting code, use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down:   Or watch this video on code formatting.
