customizing secondary menus

Hi.

I have done some custom CSS to get the small menu above the main navigation to appear below (because I need that area not to contain the main menu – in case you are wondering why I didn’t use the custom header layout options within the theme).

While I have everything looking right, now I can’t see the drop down menu items from the main nav – the smaller menu that I have moved is in front and I have tried bring the main nav forward using the following:

.avia-menu.av-main-nav-wrap {
z-index: 9999 !important;
}

but its not working. any suggestions? check it out here: http://mindsparklabz.com/dev/shred360-2/

then hover on the Our Services menu item at the top.

thanks!
