[Zope] In - tag

Hi, Martijn, thanks for the input! I'm trying to get the in tag working. <!--#in (1,2,3,4,5,6,7)--> <!--#/in--> gives me an error : System Unavailable This site is currently experiencing technical difficulties. Please contact the site administrator for more information. For additional technical information, please refer to the HTML source for this page. Thank you for your patience. Is there another possible solution. I just want to create a loop. from 1 to 7 Another point : <!--#var PrincipiaTime fmt="Date"--> gives me the date I nowhere found the PrincipiaTime parameter in the guides. Is there a guide which gives an overview of all possible parameters per tag and their explenation? Thanks in advance! Tom.
