[Zope] Lists and external methods

Hello there, I started working with Zope a few days ago, and I'm currently having some troubles with external methods. I made an external method that returns a record like list, but this doesn't seem to work correctly> The list look a bit like this: 90, "x86", "Explanation", "22/06/200" 89, "x86", "Explanation", "22/06/200" 89, "mac", "Explanation", "22/06/200" I want the external method to return this in a list, where I can iterate over using the <dtml-in> tag, so that I can reference the different fields in each record with a name. What should the list look like so that I can accomplish this? Pieter
