SwapLayers and Stay issues

[rev_mumbles]

I have a box with buttons that change the middle image it is currently working perfectly at:
Live site it is working on
(the survival benefit data table)

When I have added a set of tabs at the top to switch the bottom buttons:
(see image below) everything breaks.

I have isolated the table in the attached link to show the behavior it is now doing.

Anybody have any helpful ideas, it seems so simple (but i am def no dhtml or javascript guru, so i have been tearing hair out tweaking thinsg for two days)



Link to broken table

zip file version of page if anyone thinks that would help

Thanks again
