You're mixing up hash references with hashes in your syntax. The 9/16 is you hash in a scalar context, not the hash itself.

You want something more like:

my %hashList = ();
...
$hashList{$count} = \%secondHash;
...
my $hashtemp = $hashList{$count};
while ( my ($key, $value) = each ( %$hashtemp ) ) {
  ...
}
