In case you haven't gotten a reply already (I don't see one on quick scan).
My observation is that when variables are passed in the URL they aee typed as strings, and thus you end up with (effectively):
entryid="0"
which most certainly isn't false.
Try this:
<dtml-if "_.int(entryid)">
Or, explicitly tell ZPublisher to marshal 'entryid' into an integer: http://server/dtml.doc?entryid:int=0 This has the disadvantage of not allowing you to <dtml-try> to do it yourself and handle the error your way... -Michel
