Sigh. Design thinko. So you enter all your info: name, mailing address, email, etc. And then you use somebody else's card to register, so you change all the data.
And the data that's saved is, of course, the billing info. The data you entered originally is completely overwritten and discarded. THIS is why I wanted to test it, live, on the production server. (And have other people than the original author look at it for a bit before strangers' money was involved.) I need to fix this... Rob
