Johann Loibl wonders:

What does the following line means?

href="&dtml.url-mail_password_form;

how to work with '&' ?

This means to substitue the value stored in the variable "mail_password_form" as an "absolute URL". It's known as "DTML Entity Syntax". Check out: http://www.zope.org/Members/AlexR/EntitySyntax BTW, this is a pretty basic question, and is best addressed to the generic Zope List: zope@zope.org Later, Jerry S.
