For some reason there is an extra space at the bottom of my div You can see it here: http://lucidrealmdesign.com/clients/transitions/

I have set all of the appropriate marging and padding to 0. Any ideas?

This is the line causing the space:

<DIV id="content-a"><IMG alt="Transitions Interior Design" src="Transitions Interior Design_files/home_left.jpg" height="480" width="274"> </DIV>

REMOVE the space right before the </div> and the gap disappears.

LadynRed is correct, the extra space was causing the error.

BTW, like the site it's very sexy! Nice use of Javascript.
