Hi,
I need a custom mod for zen cart which allows me to put a separate entry called surcharge upon checkout. This module should allow me to:
1. input a fixed or percentage surcharge
2. the surcharge should be based on payment method.
3. display the surcharge at the check out payment page
4. i should be able to sort the order of display of this surcharge myself in the future under Order Total
Thank you so much
Thank you
