Thank you for the suggestions.
I don't have any problem with the the zone.
I use oscommerce version 2 which initially did not have moneybookers installed.
I have therefore downloaded the moneybookers addon files into the various folders and installed it.
I have not made any changes to the database, so all other payment modules work fine except moneybookers, which cannot display for customers to chose during checkout.
Please, I'll like to have more suggestions.
Thank you.
