Your problem is you are actually importing jQuery twice! Once in the <head>
:
<script src="scripts/js/jquery-1.7.min.js" type="text/javascript" charset="utf-8"></script>
AND once on the bottom of the page:
<!-- Grab Google CDN's jQuery, with a protocol relative URL; fall back to local if necessary -->
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="js/jquery-1.7.2.min.js"><\/script>')</script>
You need to remove the one at the bottom of the page. Please let me know if you have any questions and I will answer them the best I can!
