The link above has a main menu navigation that includes sub menu items or dropdowns on some of the buttons. The dropdowns are covered up by the Nivo slider. Can someone tell me how to fix this? I have been toying around with z-index on what I think are the appropriate html items, but I cannot figure this one out.

Thanks in advance to anyone who can help!
