you know it's a reference to a hash. good. the HASH(Ox1c6ed80) thingy is the
memory address of the reference.

your hash value is hash reference. consider:
#!/usr/bin/perl -w
use strict;
my $hash;
$hash->{a} = { a => 1};
$hash->{b} = { b => 2};
print join("\n",values %{$hash}),"\n";
__END__
see if you can figure out what prints out. if you don't know what will print
out from the above, you haven't master reference in perl yet.
not only is $hash a reference to hash. its values are also reference to
hash!
if you still can't figure out your problem, post the portion of code that
you suspect is wrong so we can check for you.
