Drop down menu product options not functioning now

-- url of the page with the problem -- : www.fricanospizzaalpine.com/order-online...-12-thin-crust-pizza
-- HikaShop version -- : HikaShop Business 2.3.0
-- Joomla version -- : 3.3.0
-- PHP version -- : 5.4.26

Most of my products found at www.fricanospizzaalpine.com/order-online have options. Click "choose options" on a product with options and you will see drop down menus to select options. The menus will not drop down anymore. They had worked before. I have tried multiple browsers and computers/iPads.

Hi,

What have you done since it was working ? Joomla update ?
Thanks to download the latest version of HikaShop from our website and install it over the current one, that could potentially solve your problem.

No changes were made recently.

HikaShop Business 2.3.1 has been downloaded and installed but the problem remains.

Please urgently help.

Disregard, I fixed it. We had added a contact form. Removing it from the online ordering pages fixed it.
