Oops, try again. Make sure you have defined all the variables!

i can’t figure out where i had gone wrong.


. 
 var main = function() {
    $('.dropdown-toggle').click(function() {
    $('.dropdown-menu').toggle();
});



    $('.arrow-next').click(function() {
       var currentSlide = $('.active-slide ');
       var nextSlide = currentSlide.next();
       
        var currentDot = $('.active-dot');
        var nextDot = currentDot.next();
       
       if(nextSlide.length === 0) {
        nextSlide = $('.slide').first();
          nextDot = $('.dot').first();
       }
       
       currentSlide.fadeOut(600).removeClass('active-slide');
       nextSlide.fadeIn(600).addClass('active-silde');
       
        currentDot.removeClass('active-dot');
         nextDot.addClass('active-dot');
         
    });
         
       $('.arrow-prev').click(function() {
  var currentSlide = $('.active-slide');
  var prevSlide = currentSlide.prev();

  if(prevSlide.length === 0) {
    prevSlide = $('.slide').last();
  }

  currentSlide.fadeOut(duration).removeClass('active-slide');
  prevSlide.fadeIn(duration).addClass('active-slide');
});

};

$(document).ready(main);
