jquery with object oriented javascript

i had an open/close tab script that worked:
http://patrickallard.net63.net/procedureoriented/
but the code was repetitive and couldnt be expanded for more functionality because i didnt have objects
now i am treating the tabs as objects, and the code is much neater with them:
http://patrickallard.net63.net/
just one problem, it doesnt work! and i have no idea why! could someone please take a look? it is short, well commented and neat and i suppose an experienced person could find the error quickly
you can find the code at the bottom of each page, and ill post it here for convenience sake
tyvm!

Really this reeks of 'javascript for nothing' and 'gee ain't it neat' nonsense, that's basically ****ing all over your accessibility given the lack of graceful degradation scripting off.

You've got nothing resembling semantic markup, nonsensical use of numbered headings, abusing STRONG for no reason inside headings (or are you TRYING to get slapped down by the search engines?), tables for layout, presentational CSS inlined in the markup, endless CSS redundancies, endless pointless DIV and classes for nothing, paragraphs around obvious heading elements, heading around content that is quite obviously NOT a heading to the subsection that follows...

... and that's without talking about pissing away your accessibility with the stupid malfing jquery animated BS, that is basically using scripting to replicate everything that was WRONG with framesets.

My advice, lose that garbage entirely and break that into actual *SHOCK* subpages -- pageloads are NOT evil, particularly if you STOP wasting 36k of HTML on 6k of plaintext -- anywhere from three to four times the code that should be used for such simple content.

Generally speaking, I think you need to learn more about HTML and building working layouts in CSS before throwing the "gee ain't it neat" scripting nonsense at the page. You've made a laundry list of how not to build a website if you care about visitors actually using it.
