When building a module I'm not sure how I pass the data from the program to the module in an OO fashion. Consider this program:

#!/usr/bin/perl

use strict;
use warnings;

use lib '/home/nhwatson/lib/perl/';
use Mine::Openview::opcmsg;

my $ovs = new Mine::Openview::opcmsg {
    msg => 'This is a test',
    app => 'Perl script',
    obj => 'Perl module',
    sev => 'warning',
    msgg => 'message group',
    ser => 'service ID'
    };

my $return = $ovs->send;

print "\nreturn = ".$return."\n";,

The module

package Mine::Openview::opcmsg;

use strict;
use warnings;

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

# Get message strings from subroutine call
my $self = shift;
my $msg  = shift; # message text
my $app  = shift; # application label
my $obj  = shift; # object
my $sev  = shift; # severity of message
my $msgg = shift; # message group
my $ser  = shift; # service id

sub send {
# Setup arguments for opcmsg command.  If the syntax 
# changes this is were you'll apply the changes.
    my $cmd = "opcmsg". 
        " msg_text=".$msg.
        " application=".$app.
        " object=".$obj.
        " severity=".$sev.
        " msg_grp=".$msgg.
        " service_id=".$ser;

    return $cmd;
}

1;

When I run the program the variables are not passed to the module. Can someone please explain how I should pass the values to my module?
