hello monks!
i have a problem parsing a hash into a sub
new_packages($fcount,%new_db);

sub new_packages {
    my %packages = $_[1];
    print "Found $_[0] packages for download: $_\n" if ($fcount > 1);
    print "Found $_[0] package for download: $_\n" if ($fcount == 1);
    print "Which one would you like to install?:\n";
    foreach my $key (keys (%packages)) {
        print "$key) $packages{$key} \n"
    }
}

i get the following error:
Odd number of elements in hash assignment at ./slackup.pl line 49.
Use of uninitialized value in concatenation (.) or string at ./slackup
+.pl line 50.
Found 3 packages for download:
Which one would you like to install?:
Use of uninitialized value in concatenation (.) or string at ./slackup
+.pl line 54.
1)

the hash has these values:
 %new_db = (1 => 'gedit-2.2.2-i386-1.tgz',
             2 => 'ppp-3.4.1-i386-2.tgz')
