Dear Monks, I've got an error if i'd like to print out a hash of hashes with a reference. 
    sub print_host_config {
        print Dumper($host_configref);
        foreach my $key ( sort keys %$host_configref ) {
            print "$key.\n";
            print "Host = $host_configref->{$key}{cmd}\n";
        }
}

But it says that:
Use of uninitialized value in concatenation (.) or string at...

The Dumper function works, so the hash of hashes is populated with the data correctly.
