I have a hash of hashes. It looks like this:
my %servers = (
    BOUVET => {
        ps3_path => '\\\\BOUVET\\resin-2.0.3\\doc\\ps3\\',
        resin_path => '\\\\BOUVET\\resin-2.0.3\\',
        contexts_path => '\\\\BOUVET\\resin-2.0.3\\doc\\ps3\\contexts\
+\',
        customizations => {
            some_key => 'some data',
            another_key => 'more data'
        }
    }
);

I want to get at all the key/value pairs in the customizations hash. I'm trying this:
foreach my $customization (keys $servers{BOUVET}{customizations}) {
        print "$customization\n";
    }

[download]
and Perl is telling me that:

Type of arg 1 to keys must be hash (not hash element) at C:\deployment\newscripts\deploy-internal.pl line 102, near "}) "

which isn't cool. Do I have to somehow tell the keys function that $servers{BOUVET}{customizations} is itself a hash?

Muchas gracias...
