Ray, the culprit has been found, it was the UPS server behavior. After removing the UPS behavior the Express PayPal button worked. However this completely defeated the purpose of why I redesigned the checkout pages in the first place. Without the shipping calculated on the checkout-alt-2.php I cannot continue with accepting a customers credit card for processing locally. This is a very unsettling limitation to the eCart software. It seems like I have to choose one payment method over another but not both on the checkout-alt-2.php page. Unless of course there is another hack I can work into the pages.
