Button for submitting form is not working, clicking it does nothing

Hello, I was wondering if someone could have a look at our website? We are using your plugin on a custom theme http://z-cam.com/. Right now this page is not working when you click newsletter, complete the modal/form with your information and click submit. <?=do_shortcode(‘[mc4wp_form]’)?> is placed inside the footer.php of our theme and the code looks like this:

<div class="popup-news">
    <table>
        <tr>
            <td>
                <div class="popup-block">
                    <div class="icon-close_icon close"></div>
                    <span class="icon-z_cam_logo"></span>
                    <h5>Z Newsletter</h5>
                    <p>Stay up to date on the latest our releases, special offers
                        & our news by signing up for our newsletter</p>
                    <?=do_shortcode('[mc4wp_form]')?>
                </div>
            </td>
        </tr>
    </table>
</div>

For some reason, even though the plugin shows connected to mailchimp I am not seeing any data posted to mailchimp and when watching the console / timeline for http requests I see nothing being posted.

Please help!
