Hi i would like to have an option it the payment methods that the user can specify how much installments he wants so he can buy a product.Depending on his choice there has to be a field that calculates the installment for each month.
To make my self clear lets say that he wants to buy a product that costs 1000 $ an he wants to pay with 5 installments. So he writes in a field the number 5 and in another field he has to see "5 installments of 200$"
No credit card involved.
I tried to do it but i can figure out how to get the value of the order price from a .module page that is responsible for an extra option in the payment methods.
I know some php but its not enough i cant figure out how to call specific fields from the page.
Sorry for my English its horrible.
Thanks i am hoping for your help.
