I don't understand the error?

I don't know what the error is

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {


            Console.Write("Enter the number of times to print \"Yay!\": ");
            String entry = Console.ReadLine();
            try {
            int index = int.Parse(entry);
            int runningTime = 1;
            while(index >= runningTime){

                    Console.WriteLine("Yay!");
                    index--;
                    }}catch(FormatException){
                            Console.WriteLine("Invalid answer try agian.");
                            continue;
                }

            }
    }
}

For some reason, you've put that "continue;" into the catch phrase block. That is unnecessary. Just delete it and pass the challange. I hope this helps! Much love!

Here's your code formatted so that the error is easier to see:

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {


            Console.Write("Enter the number of times to print \"Yay!\": ");
            String entry = Console.ReadLine();
            try
            {
                int index = int.Parse(entry);
                int runningTime = 1;
                while (index >= runningTime)
                {

                    Console.WriteLine("Yay!");
                    index--;
                }
            }
            catch (FormatException)
            {
                Console.WriteLine("Invalid answer try agian.");
                continue;
            }

        }
    }
}

When I put that code in an IDE, the complaint was that you're trying to use continue outside of a loop, which is pretty easy to see when the code looks like this. Both break and continue are only usable when they're placed inside of the body of a loop (for, foreach, while, do while, etc), but since the catch block of the try/catch is outside the body of the loop, the code won't compile.

I'd also suggest moving the while loop you have outside of the try/catch block (which might require you to move some of your variable declarations), since running the loop is somewhat of a separate task as getting and validating the input from the user. Doing that might make it clearer what you expect to sometimes throw a Format Exception, and makes the logical flow of your code easier to follow.
