Addtocart tag not refreshing page

Question

my addtocart tag is working, but it doesn't refresh the page correctly (or at all). The product is added to the cart, the alert pops up, but then the screen goes blank. When the back button on the browser is pressed, then viewing the cart shows the product that was added. How do I get the add to cart button to refresh the page correctly? Thanks!

It's hard to tell exactly what's going on but I noticed you reference the same javascript functions 3 times in that page.  You should see two instance of this exact markup:
  <!-- JS includes -->
  <script type="text/javascript">
   if (document.location.protocol != 'https:') document.write('\x3Cscript src="http://musecdn1.businesscatalyst.com/scripts/4.0/jquery-1.8.3.min.js" type="text/javascript">\x3C/script>');
</script>
  <script type="text/javascript">
   window.jQuery || document.write('\x3Cscript src="/scripts/jquery-1.8.3.min.js" type="text/javascript">\x3C/script>');
</script>
  <script src="/scripts/museutils.js?27469026" type="text/javascript"></script>
  <!-- Other scripts -->
  <script type="text/javascript">
   $(document).ready(function() { try {
Muse.Utils.transformMarkupToFixBrowserProblemsPreInit();/* body*/
Muse.Utils.prepHyperlinks();/* body*/
Muse.Utils.showWidgetsWhenReady();/* body*/
Muse.Utils.transformMarkupToFixBrowserProblems();/* body*/
} catch(e) { Muse.Assert.fail('Error calling selector function:' + e); }});
</script>
Try copying that code in your page and saving it somewhere for safe keeping in case removing it messes the site up more and then remove those two instances of script from your page.  You are calling jQuery there but are also calling it at the end of the page too so it shouldn't break it if you remove the first two instance of that code above.  Something's definitely screw because even if I manually run the add to cart javascript function in the developer console the BODY tag gets stripped completely.
I see you are using Muse and I'm not familiar with all the javascript Muse puts onto your site but try removing those two instances of the code above to make sure that isn't somehow causing the problem.
