[Zope] how to access an external method via a hyperlink

Is it possible to access an external method via a hyperlink? I am able to do that from a form: ------------------------------------------------------------------------- <form action=fshSetKat method=post> <input type=submit name=submit value=<dtml-var name> > <input type=hidden name=KategorieID value="<dtml-var KategorieID>" > </form> ------------------------------------------------------------------------- where fshSetKat is the name of the external method doing some database transactions but our client wishes to have a hyperlink instead of a submit button Thanks in advance for your help phil
