So it looks like the hash %hh has a key of 'QUESTION_TEST', who's value is itself another hash, so $value will always be a reference to that hash.

I think you need to post more code above this section, particularly where %hh hash is being defined and set up. You also need to explain what CHECKSOMETHING actually is.
