[Koha] Template toolkit puzzle 1.

[Raymund Delahunty]

We have a TT rule working perfectly in MEMBERSHIP_EXPIRY where staff receive one email wording, while students receive different wording, more appropriate for them.
[% IF (borrower.categorycode == 'STAFF') %]
  <staff email wording>
[% ELSE %]
  <student email wording>
[% END %]

But when I try to use a TT rule in the ODUE message, no email is sent at all- there appears to be an error:
[% IF (borrower.dateexpiry == CURDATE() %]
  <leavers are told to bring all their items back as their account has expired>
[% ELSE %]
  <other users are told to return their overdue items>
[% END %]

Any ideas? Is CURDATE() correct?
