On this website we sell amongst others house numbers. The price per digit is fixed (50€). There is a custom field where the customer can enter his house number. The price in the shopping basket should be calcualted as the number of digits times 50€.
E.g. if the house number is 23, the price in the basket should be 10€.
E.g. if the house number is 38a, the price in the basket should be 150€.
How can I do this?
Kind regards,
Hubert
