There are a couple of the spry assets that have not been uploaded:
SpryValidationTextarea.js SpryValidationCheckbox.css
both give 404 errors. where:
SpryValidationTextField.js
loads just fine.
also, when I first load the page, i get a javascript error complaining about the following code:
<script type="text/javascript">
var pageTracker = _gat._getTracker("UA-4626278-1");
pageTracker._trackPageview();
</script>
this could be preventing the Spry code from loading properly.
