Okay, so, I grabbed the example from HTML::LinkExtor pod, and, here's the problem. I put everything into a subroutine (my first excursion into subs), and everything works great the first call through. (in other words, subname($eh, $what) works, but when you execute the identical code a second time, it doesnt work.). So here is the symptom. The subroutine returns an array, and the array is populated the first time just fine, but the second+ time around, it wont get populated. Any Ideas? 
#!/usr/bin/perl  -I/tmp/perl/libwww-perl-5.53/lib/

use 5.005;
use strict;
use LWP::UserAgent;
use HTML::Parser;
use HTML::LinkExtor;
use URI;
use URI::URL;


my $ua = LWP::UserAgent->new;

sub extractlinks
{
    my($url, $linktype) = @_;
    
    my @sublinks = ();
    sub callback
    {
        my($tag, %attr) = @_;
        return if $tag ne $linktype; 
        push(@sublinks, values %attr);
    }

    my $p = HTML::LinkExtor->new(\&callback);

    my $res = $ua->request(HTTP::Request->new(GET => $url), sub {$p->p
+arse($_[0])});

    my $base = $res->base;
    return map { $_ = url($_, $base)->abs; } @sublinks;


}

my @links = extractlinks("http://www.ebitch.cc", "a");
my @totallinks;
push @totallinks, @links;

for(my $i = 0; $i < $#links; $i++)
{
    push @totallinks, extractlinks($links[$i], "a");
}
print join("\n", @totallinks), "\n";

When running with -w mode, I get the following errors (which I know have something to do with this, but I'm not sure what.)
Variable "$linktype" will not stay shared at lnkchk.pl line 22.
Variable "@sublinks" will not stay shared at lnkchk.pl line 23.
