I am getting a null shipping address when using the part one combination of checkout_shipping.php and checkout_payment.php. This happens when I try to create two accounts back to back on the same web browser session. The first time the billing address is copied to the shipping address, and the second time the billing address is not copied. I think that it may have something to do with this line of code, but am not for sure:
if (!tep_session_is_registered('sendto')) tep_session_register('sendto');
I appreciate your help.
