Trying to add simple contact form to Wave Fancy CSS3 Flexible Sticky Footer

We’ve added Wave Fancy CSS3 Flexible Sticky Footer code to our site and it looks & functions great, but we are trying to add a contact form to the footer menu – I have created a form and a widget, and tried adding the following code:

<li id="%1$s" class="widget %2$s">

        <?php if (function_exists('dynamic_sidebar') && dynamic_sidebar('footer')) : else : ?>
        <?php endif; ?>

</li>

but the footer menu isn’t working correctly when I add it. Please advise how we can best add a simple contact form to the footer? Thank you in advance for your help!
