Hi Ray,
If you scroll down to the "Babycake" section at cupcakes.php I tried to order any of the babycakes in both Explorer and Google Chrome using Windows 7 and on an iPad (Safari) and was not successful. Babycakes are located directly below the "Partyline" cupcakes on the above link. When I attempt to order (add to cart) it submits back to the same page (cupcakes.php)
Hope this helps. Thanks, Jackie
