So, I just want to do a hash where the value referred to by each key is a reference to another hash. 
#!/usr/bin/perl

use strict;
use warnings;

my %testhash;

$testhash{ "Tier 1" } = { "Tier 2" => "Tier 3" };

my $ref = $testhash{ "Tier 1" };

print $testhash{ "Tier 1" }, " is a reference.\n";

######  Works Great  ########
print %$ref, " is dereferenced.\n";    

######  Dies Horribly  ######
print %$testhash{ "Tier 1" }, " is dereferenced.\n";

Since $ref is the exact same hash reference as $testhash{ "Tier 1" }, why does Perl spit out "Global symbol "$testhash" requires explicit package name" when I try to dereference the latter? I'm guessing Perl thinks that $testhash is a non-existent scalar, but I can't figure out why it isn't returning as the hash reference value and derefencing it. And to prove they are the same ref: 
print $ref, " is \$ref\n";
print $testhash{ "Tier 1" }, " is \$testhash\{ \"Tier 1\" \}\n";
------------------------------
HASH(0x8dc2bdc) is $ref
HASH(0x8dc2bdc) is $testhash{ "Tier 1" }

Thanks!
