Hello, I have a hash of hashes, and want to iterate over a "subhash". What I made does not work.

I have a hash of hashes %pupils: $pupils{$class}->{$name}=$score
(the real program is very different, but the structure is essentially the same)

Now I want to iterate over the pupil-names in one class:
foreach my $nm ( keys $pupils{$class}) {
push( @namelist, $nm )
}

This does not work. How can I get it right?

Thank you,
Mo
