OK under the resources menu is an article called Resource Centre, the third paragraph has the code
{faqslider section}faqs{/faqslider}
which is from the FAQ Slider plugin, (it can be seen here in action...
www.trafalgardesign.com/faqs/plugin-faqs
)
Basically the js is being broken somehow, its all a bit over my head..
I checked your site and I see the slider and tabs there is working properly. Screenshot attached. Furthermore, this is not the template or RT extension issue. If you are using 3rd party extension, I would also highly recommend you to ask the developer regarding to their extension issue.
