Hi,

your problem is either that $lost is undefined, or, as pg has indicated, that $dbm{$lost} exists, but is undefined. You could check for definedness before going through this snippet: 

if defined ($lost) {
  if (exists ($dbm{$lost}) && defined ($dbm{$lost}) ) {
    .. the rest of your snippet 
  }
}

You might also want to check the rest of your code to find out just why either of these two is undefined, and whether that was intentional or not.
