You responded to a thread I posted a couple weeks ago about having another installation of PS3 on the site to have two separate checkouts...one for local and one for shipping long distance. I went ahead and put another checkout on the site, and that one works. However, the original one doesn't and still gives me the error message I sent you. They both have the same PP_ECO_PHP.php that you gave me, I just double checked to make sure. Could it be another file? We had some custom coding done to the shipping behaviors in the main checkout that might interfere. I've attached the error message I received this time.
