My script uses url_param's from a link to delete certain hash keys. This has never been a problem before but for some reason it's now screwing everything up. If there are three things in the hash and you delete one by pressing the link, it will delete but one of the remaining hash keys will corrupt and have a null value.

I can't for the life of me figure out what the problem of this could be. From the snippet below does anyone have any ideas?

Thanks so much for your time.

my $rem = url_param("rem"); use DB_File; my %default; my $default = "default.db"; # location of database tie %default, "DB_File", "$default", O_CREAT|O_RDWR, 0644, or die "Oop +s! $!\n"; print header, start_html; if ($rem ne "") { if (exists $default{$rem}) { delete $default{$rem}; print "<center><font color=blue>The URL was removed successfully +.</font></center>"; } else { print "<center><font color=red>That URL was not found.</font></c +enter>"; } }
