I've recently been trying to come up to speed using Data::FormValidator. It's important to note that part of the challenge for me has to do with module familiarity ... while I feel I have a sound working knowledge of Perl in general, when it comes to understanding the nuances of sending and retrieving items to modules, I find myself struggling.

Case in point - I've set up a test form with 8 fields. The first four fields are required, and the last four fields are optional. When submitting the form, I'm intentionally leaving two of the four required fields blank - I'm trying to get FormValidator to spit back some sort of error message(s).

I'm able to have the script report the missing (and required) fields, but I can't seem to get any error message reports back from the module using the $results->(msgs) call. Here's the script code: 

#!/usr/bin/perl

use CGI qw(:standard);
use strict;
use Data::FormValidator;
my $q = new CGI;
my $profile = {
    required => [qw(one two three four)],
    optional => [qw(five six seven eight)],
    msgs =>{},
};

print "Content-type:text/html\n\n";

my %fdat = $q->Vars;
my $results = Data::FormValidator->check(\%fdat, $profile);

if ($results->has_missing) {
    foreach  ($results->missing() ) {
        print "missing field name: $_ <br>";
    }
    foreach  ($results->msgs() ) {
        print "msgs output: $_ <br>";
    }
}

exit;

And here's the HTML output:

missing field name: three
missing field name: two
msgs output: HASH(0x81ff9dc)

I've got this feeling that I'm missing something very fundamental here, but for the life of me, I can't figure it out. I've searched high and low for references to results->(msgs), and was unable to understand what little I found .... any help is appreciated.
