I define a myhomepage property and can do this: <!-- #var myhomepage --> and creates this html: <a href="http://whatever.value.was">myhomepage</a>

Do I do this somewhat differently? How do you add more property types in that list?

A URL is a string of characters so you can type a URL into a string property: If I defined a string property, href_to_home_page, as follows: href_to_home_page: <a href="http://www.zope.org">Zope Home Page</a> I could use it anywhere in my DTML as: <!--#var href_to_home_page--> --Rob
