[Zope] HTML anchor using DTML?

Hi, I'm designing a static HTML pages using DTML. Basically each page is divided into 2 sections, the header and the content. such as: <dtml-var services-navig.htm> <dtml-var services-cont.htm> In some pages, the content is too long, and they are divided into some sub-content which is linked through sub-header. The website is: http://www.gem.com.sg/services.htm For the above examples, there are 3 subheaders: 'Laboratory', 'consultation' and 'onsite' If I click on the subheading, I want it to display immediately on top of the page. I can use 'Anchor' if I use the HTML FRAME But how to do this in DTML? regards, Heri
