I'm glad to see that you are on the right track. What you need to learn now is how to deal with references and data structures in perl. I would recommend that you read the references tutorial here on PerlMonks to get you familiar with how to access data structures in perl.

Now, back to D::FV. From the docs it says that the msgs method returns a hash reference. So in order to access the data you will need to know how to de-reference that hash. The folowing code should be able to print out your messages:

my $messages = $results->msgs(); # $messages now contains a hashref

# The arrow operator de-references the hashref
print "input two:  ", $messages->{two}, $/;
print "input three:  ", $messages->{three}, $/;

# Or de-reference it first and then print
my %messages_hash = %$messages;
print "input two:  ", $messages_hash{two}, $/;
print "input three:  ", $messages_hash{three}, $/;

# Or print out everything in messages
while (my($key, $value) = each %$messages) {
  print "input $key:  $value$/";
}

I have not tested the above code, but if msgs does return a hash reference then it should work.

Hope this helps...
