Tab problem?

my site is http://www.postgraduatesinsport.com

i have got the orde rof the tabs set…

problem is i seem to have the coding slightly messed as the 4 tab contents are now listed below the tabs…

i am trying to get the subscribe tab to be the default tab with the subscribe tab details in the box below the tabs. eg a blue border aroudn the tab content with a white background to the tab content.

can someone please look at the code i have for sidebar.php and tell me what i have done wrong?

thanks very much…
