"Empty Cart" message when attribues not selected

[rickj]

Hi Everyone,

My web site www.ergoware.com has a problem when users try to add something to the cart and neglect to select all the options for that product. It used to give a canned Zen Cart error message; however, now it takes the user to a page with a mesasge "YOUR SHOPPING CART IS EMPTY. Below that it shows the new products for the month, followed by featured products, and then the monthly specials.

My site does have significant customizations, but the cart did work for months. We've recently added some modules, which may be related. They include the fast and easy checkout, a module that updates the price to include the attributes add-on amount, QuickBooks Integration, Sales tax report, and an enhanced reporting capability.

My programmer has been unable to isolate the problem and I am losing cusomers as a result. Any recommendations / ideas would be MUCH appreciated!
