I need help with my website

Hello, I’m working on a website, www.coldcoffee.com/gracienew

I have a drop down meny u on there that once worked but has suddenly stopped working. I’ve racked my eyes and brain out trying to figure out the obvious. I’m probably thinking too hardand for a solution that is probably simple. I would greatly appreciate it if somebody would take a look at the site and give me some feedback as to why the drop down menu stopped working. Please email me at tranl@tranism.com

Thanks
Long Tran
