At the front end the answers to the FAQs are meant to open

Hi

At the front end the answers to the FAQs are meant to open in an accordian style when clicked - but this isn't happening on my site.

Users can see the questions ok but they can't reveal the answers. I've tried switching on/off the option to "Use Support System styles" in the settings but this still doesn't enable the answers to be seen.

Can you help me out please?

Thanks
Oliver
