[Sonnie]

Thats often caused by a 'constant variable', something that is user selectable in one place is hard coded in somewhere else.

Thanks Chuckl, I looked through the above thread, but nothing really popped out as to what I might be looking for. I'll keep going through it.

Way back in my DOS programming days, unless otherwise defined, variables defaulted to values (ie String Variables to NULL, Integers to 0, etc. Would it not be possible upon customer signup to initially hard-code in the customer's email preference variable (whatever that is) to HTML? Could this be done in create_account.php? And by the way, what IS that variable?
