Address Book project problem (listView)

Question

Hi! I'm doing an Address book project, and I have a problem, when deleting a name from list.

Let's say we have Adam, Bryan and Charlie. The problem is, when I delete Bryan, Charlie moves for one place up on the list, and looses his info. Eventually, Adam's info will be shown in Charlie's info, as well. Here is the code provided, I'd be very grateful for any help!

(The program is in Croatian... Ime = First name, Prezime = Last name, Biljeske = Notes, Traži = Search, Svi kontakti = All contacts, Spremi promjene = Save changes, Dodaj kontakt = Add contact, Ukloni kontakt = Remove contact, Isprazni polja = Clear fields)
