question regarding local-function

Hi everyone: 

   I am doing an sample exercise which demonstrate the usage
of local
function.
   the sample trying to show the localized variable in
subroutine are
not visible outside the block. I got error complains that
scalar
variable declared inside subrountine need a package.

Please see my code and help me to make it working so the
code will
working according to it's purpose. Thanks!


use strict;
use warnings;

my $first = "Per";
my $last = "Lindberg";

&greeting($first, $last);

3. print "-----$fname-----n" if defined $fname;

sub greeting
{
  local ($fname, $lname) = _;
  5.print "Welcome $fname!!n";
}

 The output for line 3 and line 5:
 3 <no output>
 5 Welcome Per!!

You really shouldn't worry about local() until you
absolutely need it.

If you're looking at a tutorial that teaches
"local" instead of (or before)
"my", or mentions "associative array",
please stop looking there.
