Thanks, Ray. I inserted the code on the confirm.php where you suggested and it does bypass a wholesaler through to checkout_success.php. However, the store to database behaviors are on the pp_confirm.php page, which I bypass - my flow for a wholesaler is now checkout.php to checkout_success.php. I tried inserting the code above the <doctype> on the pp_confirm.php ... but, of course, I don't get to that page now. I did try removing the trigger change above on confirm.php, instead only adding your code on the pp_confirm.php where the database details are stored, but I end up back on the checkout.php page.
Also, when I do pass through to the checkout_success.php page as a wholesaler, the shipping info from the checkout.php is not shown. I haven't taken a closer look yet at the variables ... just asking in case it is much more obvious to you. :)
