Hrmm, that doesn't look like 47 lines of code. You're not showing enough to say for sure, but my guess is that the code you have shown is inside the BLOCK of a while or for loop, and then you're getting the errors in subsequent code outside the loop where %temp_hash is no longer in scope.

You need to consult Coping with Scoping (google for mjd perl coping with scoping; it's too early in the morning for linking).

Update: Oh, yeah I didn't even catch the scalar part of the error messsage (ENOCAFFEINE). Possibly you're trying to use $temp_hash as a hashref (e.g. $temp_hash->{$foo} or ${$temp_hash}{$foo}) later, again outside the scope in which %temp_hash was declared.
