COWOA (for ZC v1.5.x)

[DivaVocals]

http://www.carnal-pleasures.com/zencart (apologies that it's an adult site)

Order the free book in the left sidebar. You'll see the error crop up when you use the COWOA checkout. :-)

Thanks for the heads up about this being an adult site..

As temp workaround, go to this file: includes/modules/custom_template/no_account.php
Try modifying lines 217-218 as follows:

217 $firstname = Valued ;
218 $lastname = Customer;

Please note there is a space after "Valued". This is UNTESTED, but it should work..
