Thx for fast response,
I checked Display > Custom fields, it has no fields for contact form, except the one, that was created by me for telephone numbers.
Am I missing something? You can check attached image, I was asking about "name", "email" and "additional information" fields in contact form.
How are you handling this one click order ?
No, I simply use provided by client information to create the order manually afterwards. It` not ideal solution, but it is mandatory, because some customers can`t make order at all through our website.
