The reason mine didn't work then was because I entered the email address AFTER the order had been entered and it had been invoiced.

IMHO this is confusing.

I think I can make what I want to do (email confirmations then email invoices) work but I can't then add emailing of statements (not enough email address slots to work with). The alternative would be to require a ship to address for every customer use that to hold the address that is to receive confirmations. Or maybe I'm missing something.
