I keep getting the error message, "Remember to fade out the current slide and remove the 'active-slide' class."


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();
    }
    
    if(nextDot = 
    currentSlide.fadeOut(600).removeClass('active-slide');
    nextSlide.fadeIn(600).addClass('active-slide');

    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(600).removeClass('active-slide');
    prevSlide.fadeIn(600).addClass('active-slide');
    
});   
}; 
    
    
    
    $(document).ready(main);
