Need dropdown menu help in CSS

Since I’m still new to coding, but can create good mock ups in illustrator as well as build a site from the wp back end, we outsourced the skinning of this site. It’s running on a custom child theme of Genesis.

I’m suspecting something in the child’s CSS is preventing the dropdowns from working, since the menus are already built in the WP back end, they just don’t show. Here’s the nav section of said CSS. Any help would be appreciated. Thanks.
