How are you calling each/keys/values? If your hash is a reference, it should be something like keys %$results.

You could also do :  my %real_hash = %$results which will attempt to copy your hash, but will not do a deep copy. If you need a better copy, you can use the Clone module to do that.

It's not what you know, but knowing how to find it if you don't know that's important
