Ray, I have another problem of how I am adding the 4 recurring value fields to the shopping cart. I have two fields that are pulled from the database and two fields that are pulled from select lists. If a customer tries to make a purchase of a non-recurring payment item then they get an error at checkout because I am not sending all 4 recurring payment variables to PayPal. I looks like I need to revisit how I am sending the data to the shopping cart. I probably need to have all 4 fields as drop down lists so that no recurring payment data will be send to PayPal when a customer make a regular, non-subscription purchase.
