fields in kaddressbook

Hello, in kaddressbook I have problems importing the birthday from a csv file. For any item I selected unquoted during the import procedure. It doesn't work with the plain text option either. How can I import the birthday? Do I have to change the birthday format in the csv file first? To which? Now I use dd.mm.yyy (German KDE). Can I change Additionally not all kaddressbook fields (from within the contact editor) are availbale in the import dialog, e.g. category, URL. Can I determine somewhere which fileds (or all) are available in the import dialog? sunny regards Stefan
