I'm having trouble returning data from a module I'm building.

Calls the module: 

my (@cols, @hw) = new Itiv::Hw->all_hw($dbh, $filter);

The module: 

package Itiv::Hw;
use Exporter;
use lib "/var/www/itiv/modules";
use DBI;
use MHQ::DBI qw(:all);
use warnings;
use strict;
use vars qw($VERSION @ISA @EXPORT);

our $VERSION     = 1.00; 
our @ISA         = qw(Exporter);
our @EXPORT      = qw(&new &all_hw);

sub new {
    my $class = shift;
    my $self  = {};
    return bless $self, $class; 
}

sub all_hw {

    my ($self, $dbh, $filter) = @_;

    my $statement = 'SELECT 
    hardware.hid as Hardware,
        description as Description,
        DATE_FORMAT(created, \'%Y-%m-%d\') as Created,
        received as Received,
        hw_type.type as Type,
        model_number as Model,
        manu_serial as Serial,
        poid as PO,
        hardware.hid as HID,
        users.uname as User
        FROM hardware, users, hw_type
        WHERE hardware.uid = users.uid AND hardware.hwtid = hw_type.hw
+tid';

    if ($filter ne 'none'){
        $statement .= " AND hardware.hwtid='$filter'";
    }
    $statement .= " ORDER BY description;";
    
    my @cols = qw/ Description
        Type
        Created
        Received
        Model
        Serial
        PO
        HID
        User/;
    
    # gets list of hashed structure
    my @hw = dbi_exec_for_loh($dbh, $statement);
    return (\@cols, \@hw);
}
1;

Cols ends up having 2 or 3 entries, instead of 10. Hw is empty.
