[Zope] Using <dtml-return...>

[Laura McCord]

Hi,
 I have a form in a zope page template and when the form is submitted it
uses a dtml method to process this form. In the dtml method I have this:
 <dtml-let msg="ValidateForm(username = username, curpasswd=curpasswd,
passwd1=passwd1, passwd2 = passwd2)">
 <dtml-return msg>
</dtml-let>

How do I send this back to the page that contains the form? I read that
you use dtml-return but how do I display the results in the zope page
template.

Thanks,
 Laura
