It is me who posted anonymously since we aren't allowed to log in at the university.
I didn't get where I missed "sigil $ in line once".
Furthermore, i am getting errors such as Use of uninitialized value in line 34 at variables $row and $fields at the penultimate line.
So when i place the  print $row if exists $hash{$fields[0]}; after the loop it gives an error "Perl requires explicit package name"
i am really a novice at this if you could guide me in this I would learn more.
