[Zope] Passing parameters to a dtml method from zpt

[Laura McCord]

I have a dtml method, sendMail, that sends out an email:

<dtml-sendmail smtphost="MailHost">
To: 
From: 
Subject: Email
</dtml-sendmail>

I need to pass a value to be used in the To: section of this sendmail.
from the zope page template I have this:
 <a tal:attributes="href string:sendMail?email=email"....>email</a>

Can anyone help me with this?

Thanks,
 Laura
