Hi Kevin,

Thanks, this is definitely closer.  In the product directory photoCD I
have ZClasses multiRes and photoCD.  I'm in an instance of a photoCD
class(which inherits from Folder) somewhere in my site and I am trying
to add an instance of a multiRes. So I added this to my method in
photoCD.

<dtml-with "manage_addProduct['photoCD']">
<dtml-call "multiRes_add(_.None, _, NoRedir=1)">
</dtml-with>

since I want something in the photoCD product directory and what I
want is a multiRes ZClass right?  So If I do this I get the following
odd error message:

Error Type: AttributeError
Error Value: _u

Here is part of the traceback:
...
 File /usr/local/Zope-2.0.0b3-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 148, in render
    (Object: manage_addProduct['photoCD'])

  File /usr/local/Zope-2.0.0b3-linux2-x86/lib/python/App/FactoryDispatcher.py, line 126, in DestinationURL
AttributeError: (see above)

If I call multiRes_add with no paramaters then it calls it properly
but the name space is wrong.  Any thoughts?

Thanks a lot for your help I really apreciate it.
