why are my tabs jacked up in IE6?

why are my tabs jacked up in IE6?


Please use the tabs-powered list on the bottom right side of my
homepage:
http://www.fourthavenuechurch.dreamhosters.com
When the secondary tab is selected, the initial div becomes nested
within the newly activated div. What gives? I can't seem to figure it
out.
I'm using:
jquery-1.2.3.pack.js
jquery.tabs.pack.js
I even tried changing my tabs plugin to idTabs.js, which did the exact
same thing :(
Thanks in advance,
Brad
