Can someone give me tips what have I missing here ? Thanks.

I got error saying that cant use a variable "unos"

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            int br=int.Parse(Console.ReadLine());
            int i=0;

              while(i<br)
            {
              var  unos=0;
                Console.WriteLine("You must enter a whole number."); 
            while(true)
            {
            try
            {
              var  s=Console.ReadLine();
                int unos=int.Parse(s);

            }
            catch(FormatException)
            {
            Console.WriteLine("this is not a valid input");
                continue;
            }
            }
                  Console.WriteLine("Yay!");
                i++;
            }



        }
    }
}

You're declaring that variable more than once.

The compiler is talking about line 22 where you have:

                int unos=int.Parse(s);

But there is a previous declaration on line 15:

              var  unos=0;

And it also looks like you have too many loops — make sure your program can end. 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.
