Hi,

How can i do custom fileds with variable prices depending quantities.

For example:
quantity: 100 (15,00€)
               200 (25,00€)
finishing print: with lamination (0,00€)
                        without lamination ( + 10% the value of quantity: 100= 15,00€ + 10% / 200= 25,00€ + 10%)

Regards
