Show All / Hide All links for FAQ?

Show All / Hide All links for FAQ?

Hi Guys,

I'm using a simple jQuery show/hide toggle effect for the FAQ on this page:

http://www.buttecommunitybankproperties.com/resources/faq.php

I would like to add Show All / Hide All links to the top and bottom of the page that will show and hide all answers at once. I'm stumped. Can anyone help?

Many thanks.
