hello

in a shop (HikaShop Business) my customer offers vouchers (not yet visible). these have to be personalised, which is why first name and surname have to be entered for the product. i can implement this well with custom fields. The problem: when the user wants to order two vouchers, only one field is displayed, but there should be two, one for each voucher ordered. how can i set up a custom field so that it reacts to the quantity input?

Regards,
Stefan

Ok, thanks for the answer. I will now use a textarea field where one name can be noted per line - let's see if that proves successful.

Making the custom fields dependent on the quantity would be a nice feature for a next version. Especially for products that can be customised, this would be great.
