A fair guess is that you don't need anything there. Either the entered string will be passed to CheckDate or it is in $_ when CheckDate is called.

However you probably need to use \&CheckDate rather than CheckDate().

Update: the record.pl example confirms that the entered string is passed in $_. Note that, apart from the comment at the start of the sample code, the record.pl and require.pl examples are identical.
