Hmmmm.  What happens when $row->{$key} is "0"?  What happens when
undef is set in a loop within a loop?

I think the real fix is to find a way to use exists() rather than
defined() when looking for the variable setting.  That way it doesn't
matter what the value of the var is, just whether it's set or not.
Maybe you could give that a try?
