Steve,
You need to declare $month in a separate line. The variable may not
exist if the statement evaluate to false. I think that's what it is
complaining about.

Don't rely on testing $@, simply because it is
a global variable that can get changed everywhere.
Instead, test the return value of the eval itself.
