ahhh, I see. Again though, it does appear from what you've posted that $value DOES contain data, and if that's the case, all of your tests will be true.

One way to see if I'm correct in thinking you've got a defined value (hashref) is this:

print "it's a hashref\n" if ref($hh{'QUESTION_TEXT'}) eq 'HASH';
