Ray, it's not saving to database - neither the order summary or order details. Yes, it gets to the checkout page, and it displays the "Please Wait" when you click on "Continue" but the page just Refreshes.
Do you think this is something you could assist with in the Premier Support session we're planning. I feel like I'm going round in circles with it all. Every page has failed.
I see you've added WAVT_confirmcart_Errors, but I can't decipher what those errors mean.
