jQuery slick carousel plugin not working

For the slick carousel plugin to work you need to set a few VALID settings.Yours is not working because of setting-name: setting-value.Here's a working example.All the references are added via the CDN so you can just copy and paste it as is in your page and it will work:

<head>
    <title></title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.3/jquery.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/slick-carousel/1.6.0/slick.min.js"></script>
    <link href="https://cdnjs.cloudflare.com/ajax/libs/slick-carousel/1.6.0/slick.min.css" rel="stylesheet" />
    <link href="https://cdnjs.cloudflare.com/ajax/libs/slick-carousel/1.6.0/slick-theme.min.css" rel="stylesheet" />
    <script type="text/javascript">
        $(document).on('ready', function () {
            $(".regular").slick({
                dots: true,
                infinite: true,
                slidesToShow: 3,
                slidesToScroll: 3
            });
        });
  </script>
</head>
<body>
    <section class="regular slider">
        <div>
            <img src="http://placehold.it/350x300?text=1">
        </div>
        <div>
            <img src="http://placehold.it/350x300?text=2">
        </div>
        <div>
            <img src="http://placehold.it/350x300?text=3">
        </div>
        <div>
            <img src="http://placehold.it/350x300?text=4">
        </div>
        <div>
            <img src="http://placehold.it/350x300?text=5">
        </div>
        <div>
            <img src="http://placehold.it/350x300?text=6">
        </div>
    </section>
</body>

Output:
