Thanks, you were correct, some files were in the wrong place. The readme states that unzipping the files in the catalog directory will lead to everything being in the right place. This correct, but I still got confused because of the second includes folder in the admin directory. Perhaps a line could be added to the readme noting which includes folder it goes in for us novices.

This is a great program, by the way, good job. I did the suggested modifications to display entire shipping service in the invoice and packing list. (UPS Next Day vs. UPS). This is important for me because I need to notice when a customer has upgraded shipping.

Thanks again!
