I'm currently working with Spry Tabbed Panels in a Site. I've nested a set of panels inside of another set of panels. My problem is that 2 out of 4 tabs in the first panel don't work. And two out of four tabs in the nested set of panels don't work.
Here is a link to the site for an example: http://emilymagnuson.com/trustbank/index.html
Your HTML structure looks broken. You need to fix that if you want spry to work properly. For example on line 336 of the source code there is an extra </div>
closing tag. I would review your code and make sure that all your HTML elements are placed properly.
