[Zope] my code doesn't render the if *OR* the else!

[Matthew Parslow]

I have here some Code I'm using to mail people their passwords.
when get_returner_id doesn't have a ContactEmail value, it hsould say "you
don't have an entry blah blah", but it displays nothing.
if there IS an entry, it works fine.
just wondering wtf is going on here.
(sorry about the code posting)

<dtml-if Email>
  <dtml-in "get_returner_id(field='ContactEmail',value=Email)">
    <dtml-if ContactEmail>
      Your Password has been emailed to the contact email listed in your return ID entry, <dtml-var ContactEmail><P>
      <dtml-sendmail smtphost="mail.umd.com.au">
To: "UMD Customer" <<dtml-var ContactEmail>>
From: "Unique Micro Design, Service Division" <matt@umd.com.au>
Subject: Your returner ID and Password


Someone has requested to be emailed your returns ID password
Your return ID: <dtml-var ReturnerID>
Your Password:  <dtml-var Password>
      </dtml-sendmail>
    <dtml-else>
      I'm sorry, a match was not found in the database.<P>
      <A HREF=mailpassword>Back</A>
    </dtml-if>
  </dtml-in>
<dtml-else>
(email entering form here)
</dtml-if>
