I am using Perl Tk to build a short database of contact information which I have stored in a hash of arrays. See code below please. Everything works fine except for the part related to traversing my records. While my next and previous buttons are fine, my records are not processed properly. Only one field is updated! What am I missing? I admit my script is very clunky. Any suggestions are very much welcome. Thanks a lot guys.

Tk maestroes out there, a tk database book would be a great seller. I know of a number of people, including myself, who would pay anything for a book entitled SQLite and Tk! Any volunteers:}
