Awake theme, tabs

Hi

I am working on the tabs on my page. My tabs have usually worked fine but now there seems to be a problem. The first tab works fine but the next ones not: http://maxwin.fi/kennel-maxwin/pentueet/k-pentue/ If you try to click the 2nd etc. tab it takes you on the top of the page.

Does anyone have an idea what could be wrong?
