Right now we are trying to set up a product with two variants that are required (radio button & dropdown list) - if I just click add to cart it refreshes the product details page without any of the details on the page - just the tabbed descriptions. It does not say that the item is required it just displays a mostly blank page.
The other thing that happens on the product details page is if I choose "yes or no" or choose a different size it does the same product details page refresh with only the tabbed section in the page. I'm running this install of Smith Cart in DNN 6.0.
Thanks.
