I have implemented the paypal express module in my Oscommerce online store. The process works fine until I also install a shipping module (UPS or USPS). Another words, if I use the flat or table shipping methods, paypal express works fine but if in conjunction with ups and/or usps shipping methods, I am having issues. When either of these modules are chosen for shipping method and a client uses the paypal express feature to pay, they are returned to my oscommerce site but to my dismay, they are returned to a blank page. I desperatly need some help. I have tried the oscommerce forums for a couple days now but I am not getting anywhere there. Your help will be greatly appreciated. Thanks Joshua
