Where have i gone wrong?

Ive added the try catch but cant seem to know where i made a mistake?

Program.cs 
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.");
            }

Hi there! It would be a lot to break down the changes that I have made, so I will post the final code I came up with, with plenty of added comments, read through them and you will see the changes I made.

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
           //I changes the variable names to be a little easier to read.
            int count = 0; //start up our counter variable for the while loop
            int varInput = 0; //start up our converted input (input in integer form)
            Console.Write("Enter the number of times to print \"Yay!\": ");
            var input = Console.ReadLine();   
            try
            {
            varInput = Int32.Parse(input); //For this we do not want a float, but rather
                   //an integer, if its not an integer we catch the error below

            } catch(FormatException)
            {
                //Console.Write("You must  enter awhoel number.");
                Console.Write("You must enter a whole number."); //We have to make sure this is spelled 
                                //exactly how they ask for it... This is the way the code challenge 
                                 //requires it... best to copy and paste (without the quotes).
            }

            while(count < varInput) //while our count variable (0) is less than the input requested number of times
              {
                 Console.Write("Yay!");
                 count++; //increment our counter by 1 (same as "count = count + 1" or "count += 1"
            }


        }
    }
}

In this system there is no need for boolean variables. The code challenges are very picky so its best to copy and paste the text they are asking for, and stick strictly to what theyre asking for. I know its fun to code what you want but the code challenges are strict. Hope this helps, take care and happing coding!
