Help with Tab Menu script

[bigalo]

1) Script Title: Tab Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex1/tabmenu.htm

3) Describe problem: I'm stuck and would like some help. I have a horizontal tab structure with subtabs. Right now the main tabs are activated onclick and they show their respective subtabs. I would like to add the same functionality to the subtabs so that when they are clicked, the style changes and the clicked subtab shows as active. I would also like to have the cookies applied to the subtabs and subtab contents as well. Can anyone please help?
