possibly dumb question

Hi jQuery gurus,

I am new to the wonder that is jQuery, and am working on a page located at: http://www.ibiblio.org/storytime/NEW_SITE/submit.php

I want to put in a link that onclick will make all the divs in the accordion slide down. I'm sure the answer is really simple but I've been looking at it for too long and it eludes me. Any advice will be much appreciated!
