I'm under the impression that by assigning a single value to a hash it becomes
the key with the value being null.

Actually, the double declaration was a mistake that I had seen immediately after
posting last time. I took it out but the error didn't go away.

I did as you said and dereferenced each of those methods. Now, instead of
getting "5" in the error, I'm getting "72". These numbers correspond to user
IDs. I don't know why it is telling me "Can't use string ("72") as a HASH ref
while "strict refs" in use at ./user_timesheet_new.pl line 27."
