Web Site Payments Pro/Express Checkout Issue

I am using Web Site Payments Pro and including the Express Checkout option on the checkout page. When I use the Credit Card option, it's writing the customer's address information to the database just fine, because I'm able to reference the fields from the checkout form. However, when I use the Express Checkout option, the address fields are coming up empty in the orders table because the Store Cart Summary in Database server behavior is referencing form values, and there don't appear to be any valid form values for it to reference. I'm requiring a login prior to the checkout page if a customer's session ID variable isn't in place, so the address fields on the checkout form are being filled in for me automatically. Should should I just save those form values as a session variable when using Express Checkout? Is there an easier way to do this?

Has anyone else encountered this issue and how did you solve it? I'm getting ready to scrap the Express Checkout option...

Thanks!

Okay - never mind. I got this to work. Seeing that a login was required BEFORE the checkout page, the system already knew who the customer was, so I was just able to pull the info from that recordset when using Express Checkout. Sorry if I wasted anyone's time :)
