I was pretty sure the problem was that I was losing context when calling get_rid() - but for the life of me I cannot figure out how to pass it on - trying: <dtml-var expr="get_rid(_.None, REQUEST)"> still gives me the NameError for next_rid - but the first one works: <dtml-var expr="get_rid(_.None, _)"> Anyone care to illuminate me as to why (what am I doing with the call above? Thanks, Martin

The DTML method call:
<dtml-var expr="get_rid()">
Will call get_rid without a "namespace", so get_rid can't lookup next_rid, and therefore it fails. Try this:
<dtml-var expr="get_rid(_.None, _)">
Try the Zope "Help" link from the management interface, go "Zope Help", "Zope API", "DTML Method", and lookup the API for __call__:
__call__(client=None, REQUEST={}, **kw):
So, clearly this will work:
<dtml-var expr="get_rid(_.None, REQUEST)">
Namespaces are hard!
