[Zope] Error Value: Can't add Tutorial

[Leonard Sitongia]

Environment:
FreeBSD 4.2
Python 1.5.2
Zope 2.3.2
Apache/PCGI
Netscape 4.7

I've installed Zope, running with Apache.  I've used the super manager 
account to create my user account.  Logged in as my user account, I
try to add the Tutorial, and get:

Error Type: Bad Request
Error Value: The ZGadflyDA product must be installed!

ZGadflyDA is in the Products list.

The Apache log says:

 10.0.1.99 - - [30/May/2001:12:35:57 -0600] "POST 
/Zope/Sitongia%20Home/manage_addProduct/ZopeTutorial/addTutorial HTTP/1.0" 
400 1933 
"http://odo/Zope/Sitongia%20Home/manage_addProduct/ZopeTutorial/tutorialAdd" 
"Mozilla/4.76 [en] (X11;
U; FreeBSD 4.2-RELEASE i386)"    

Anyone know what I'm doing wrong?

Thanks,
==Leonard
