Hello
I have created a simple database with Nr_id, Sex, DataUrodzi, these data are taken from the query to the list on the form. If there is a need to change data, double-click on a given record on the list, which automatically fills in the fields NR_id, Plec, DataUrodzi, and after editing the data in the above-mentioned fields, click on the "Confirm data change" button. Changes are saved. Then I click the "Clear form" button, which clears the fields NR_id, Plec, BirthDate and if the next step is to click "Close form", the message " The index and primary key cannot contain NULL values ". Can someone tell you how to get rid of this message (where did I make a mistake)
kisses
