Lightning response ... wow - thank you. I implemented the code and the outcome is almost perfect. No additional UE - no duplicate entries for the same emailID, but the page coding still creates a new random code and replaces it in usercoupons over the one that was originally distributed to the subscriber and, with no UE generated, they will be trying to apply a non-existent one. Best way to not produce the second (or, more) code at all? Again, thanks for the help.
