Doug,
 
Thanks for the help. This got me where I need to go.

       What you have there should work. You could also simplify it with 
loops or slices:

for my $name_key ( qw( FName LName Nickname ) ) {
$validtn_hash{ Name }{ $name_key } = $input_hash->{ $name_key };
}

# OR
$validtn_hash{ Name }{ $_ } = $input_hash->{ $_ } for qw( FName LName 
Nickname );

# OR
@{ $validtn_hash{ Name } }{qw( FName LName Nickname )} = @{ $input_hash 
}{qw( FName LName Nickname )};
