Greek Online Shop (OSCommerce)
Need to change the way that the points redemption is calculated on Frontend and Backend and writed on "orders_total" Table on field "ot_subtotal_ex".
Now the calculation of "ot_subtotal_ex" field is as bellow
ot_subtotal_ex = Net product prices net
I want the "ot_subtotal_ex" to be calculated as follow if a points redemption is present
"ot_subtotal_ex" = Net product prices - ot_redemptions
files that are used as I know (attached)
admin/[login to view URL] ->lines 1858-1891
[login to view URL] ->find [login to view URL]
admin/includes/functions/[login to view URL] ->lines 2211
necause it's a module maybe this to
includes/modules/order_total/[login to view URL] or [login to view URL]
see attached pictures after changes it must look like the pictures nr-2
End finaly apply the changes on admin/[login to view URL] (its a file from wich you can edit/change the order)
