Hi, I don't want to spam the chatterbox anymore, but I am still stuck on how to sort a nested hash within a hash of hashes. 

# here's my test hash
my %hash;
$hash{"Rock Bands"}{"Smashing Pumpkins"} = "5 stars";
$hash{"Rock Bands"}{"Aerosmith"} = "5 stars";
$hash{"Rock Bands"}{"Foo Fighters"} = "5 stars";
$hash{"Pop Bands"}{"Duran Duran"} = "5 stars";
$hash{"Pop Bands"}{"Blondie"} = "5 stars";

foreach my $key (sort keys %hash) { 
    # this bit sorts ok
    print "KEY: $key \n";
    while (my ($nestedKey, $value) = each %{ $hash{$key} } ) {
        # but I can't work out how to sort this iteration
        print "nested key: $nestedKey \n";
    }
    print "-------\n";
}

This returns:

KEY: Pop Bands
nested key: Duran Duran
nested key: Blondie
-------
KEY: Rock Bands
nested key: Foo Fighters
nested key: Smashing Pumpkins
nested key: Aerosmith
-------

But I would like it to return:

KEY: Pop Bands
nested key: Blondie
nested key: Duran Duran
-------
KEY: Rock Bands
nested key: Aerosmith
nested key: Foo Fighters
nested key: Smashing Pumpkins
-------

Any suggestions would be welcome, thanks!!
