In ver. 5.0.6 I added the customer email address to the Invoice Email (client request) by adding %%Global_CustomerEmail%% in invoice_email.html and order.invoice.tpl. This worked fine.
Trying to do the same in ver. 5.5.2, but there is no order.invoice.tpl in this version. Tried adding it to invoice_print.html, but still no luck.
Anybody have a suggestion on how to accomplish this in 5.5.2?
Thanks!
