I am using the following plugin:

http://unslider.com/

Here's the code on their page that they say I can use to display prev and next:

<!-- The HTML -->
<a href="#" class="unslider-arrow prev">Previous slide</a>
<a href="#" class="unslider-arrow next">Next slide</a>

<!-- And the JavaScript -->
<script>
    var unslider = $('.banner').unslider();

    $('.unslider-arrow').click(function() {
        var fn = this.className.split(' ')[1];

        //  Either do unslider.data('unslider').next() or .prev() depending on the className
        unslider.data('unslider')[fn]();
    });
</script>

This is what my looks like:

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1.0, width=device-width" />
            <link rel="stylesheet" href="/unslider-master/site/pages.css">
    <link href='http://fonts.googleapis.com/css?family=Open+Sans:400,600' rel='stylesheet' type='text/css'>
    <script src="//code.jquery.com/jquery-latest.min.js"></script>
    <script src="http://site.com/unslider-master/src/unslider.js"></script>
    <script type="text/javascript">
    $(function() {
    $('.banner').unslider();
});
    </script>
    <script>
    var unslider = $('.banner').unslider();

    $('.unslider-arrow').click(function() {
        var fn = this.className.split(' ')[1];

        //  Either do unslider.data('unslider').next() or .prev() depending on the className
        unslider.data('unslider')[fn]();
    });
</script>
<script>
    var unslider = $('.banner').unslider();

    $('.unslider-arrow').click(function() {
        var fn = this.className.split(' ')[1];

        //  Either do unslider.data('unslider').next() or .prev() depending on the className
        unslider.data('unslider')[fn]();
    });
</script>

This what i am including for JQuery:

code.jquery.com/jquery-latest.min.js

I put it on my site but when I click on next slide or previous slide it doesn't work. I get no errors. It's just clickable but nothing else. Am I missing something? I am putting this script in the head. I am new to JS so a bit confused. Please advise. Thanks!
