in reply to Table building confusion Help Wanted

My initial reaction is to ask why you're doing it this way? Arrays and list indexes are not your friend, usually. Hashes, on the other hand, are:

use strict; use warnings; my %entity = ( A1 => { customerID => '007', ssn => '999-99-9999', relationship => 'self', }, B1 => { customerID => '008', ssn => '888-88-8888', relationship => 'spouse', }, C1 => { customerID => '009', ssn => '777-77-7777', relationship => 'son', }, ); foreach my $e (keys(%entity)) { print "$e\n"; print "$entity{$e}{'customerID'}\n"; print "$entity{$e}{'ssn'}\n"; print "$entity{$e}{'relationship'}\n"; }

And for that matter, this code could be improved, but you're starting to get the idea- you might want to change the primary key away from entity to customerID, for example, but it still largely holds. You're doing a lot of data thrashing, but not what I assume your intended goals are.

If you want to continue using arrays, I definitely suggest you follow jeffa's approach, then.

As far as putting them into a table for referencing purposes, depending on what you mean, I may have just done that for you. If you're looking to put them in a database, you should check out DBI.

As far as what's causing your problems, I can't tell from the code you presented above. At a glance, it looks like it should work.

Hope this helps!
