hi pacochin and aramil, i am now in the same situation and im stuck!. ok, i downloaded pacochin's tutorial and read it. when i try implementing it, i created a new payment module in VM, i key in the same values as listed in the tutorial. i copied the codes in the pdf apenddix and save it as the same filenames just to tryout
after typing in the codes in the extra payment info, and press save. it saved ok. But when i GO back in so that i can key in the values unde the Payment Method Form configurations, i get a WHITE page with the inout values for the Code etc still there BUT the config page tab empty. It also has an error called cmThemeOffice undefined. Please do help.
below attached the 2 images of error i got. please advise.


Besides this after reading the pdf tutorial, i also noticed that the location in which pacochin mentioned the files to create and its location. I noticed that the locaiton of the files are stated as
administrator/components/com_virtuemart/html/classes/payment/But this is weird. Shouldnt it be: administrator/components/com_virtuemart/classes/payment/
together with all the other default payment methods? am i missing something here? please advise. thanks
