Still nothing . . .
. . . the shipping info on the "CustomerInfo" page is not updating with the billing info. Now, "checking the box" doesn't have to fill out the shipping form entries on that page IF the fields are populated on the "Checkout" page . . .
But, they're not - no billing/shipping info is appearing on the "Checkout" page, just the "Shopping Cart" values (see previous post re: some blanks there, as well). I re-built the pages (last night) to ensure that I hadn't missed a step in the Recipes. I've just tried looked over the field info/PHP structure on the "Customer Info" & "Checkout" pages, but I'm not sure what to look for!
There must be something to break the logjam . . .
