The jquery validation seems to be working on that page... what should I be looking at?
I do see another unrelated javascript error on the page... you should move the jquery includes:
<script src="../_/js/jquery.js"></script>
<script src="../_/js/foundation.min.js"></script>
to the top of the page since you have a script referencing jquery up there:
<script type='text/javascript'>
$(document).ready(function(){
$('.popbox').popbox();
});
</script>
