Tabs problem (they are not "active")


Hello! As I am new user and not allowed to use links and pics, so I try to describe.

I put the tabs to my blog whith the help of post named "jQuery “Tabs Shortcode” For Blogger!" Exactly as it was written there.

They work fine, but they are not marked as active, neither when page loads, nor when I click on them. Tabs remain white, but according to css style they have to be green,

Hope someone can help me to find the mistake, thanks.
