Fellow Monks,
I know, sounds elementary, but this one has a slight twist I'm not getting my head around. I'm untainting user input and generating error messages. I have the following working fine, but would like to change things to include my error messages in the Validate module and not my script (just for cleanliness). So, the original (stripped down for clarity): 
#!/usr/bin/perl -T

print "Content-type: text/html\n\n";
use lib "/home/wbc/www/perllib";
use warnings;
use Validate; 
use strict;
use CGI;

   my $query = new CGI;

   my $age   = Validate->numbers ($query->param('age'));
   push @errors, "Please, use only numbers.\n" unless $age;
        
__END__

package Validate;

sub numbers {
   my ($class, $value) = @_;
   return unless $value =~ /^([0-9 \.-]*)$/;
   return "$1";
}
1;

And what I would like to do...
Something like this, but I know this isn't right, and nothing I tried is working. 
#!/usr/bin/perl -T

print "Content-type: text/html\n\n";
use lib "/home/wbc/www/perllib";
use warnings;
use Validate; 
use strict;
use CGI;

   my $query = new CGI;

   my $age = Validate->numbers ($query->param('age'));
   push @errors, $msg unless $age;       #something like this but know
+ it's not correct
        
__END__

package Validate;

sub numbers {
   my ($class, $value) = @_;
   my $msg = "Please, use only numbers.";
   return unless $value =~ /^([0-9 \.-]*)$/;
   return "$1";
}
1;

So, how do I define the error message in the module and then pass it back to the calling script?

Thanks in advance.
