[Zope] confusing access error

[Matthew Wilbert]

I am getting an access error I don't understand at all,
which makes me think I have some basic conceptual problem
which I hope you can help me get past.  I have never used
ZopeFind before, so that may be part of it.

I have a DTML method that looks like this:

<dtml-var standard_html_header>
<dtml-in "ZopeFind(this())">
  <dtml-with sequence-item>
  </dtml-with>
</dtml-in>
<dtml-var standard_html_footer>

I actually want to put something in the <dtml-with>, and
add some additional parameters to the find, but just trying
to execute the method as written I get the following Zope error.

Zope Error

Unauthorized: (see above)

If I replace the <dtml-with sequence-item> with 
<dtml-with sequence-index> or <dtml-with sequence-key>, I get no error, and if I display them I see the right thing.

There is only the root acl_users folder around, and it has only one user set up with manage priv's for pretty much everything.  That user can do anything I have tried except run this DTML method.  When I try to run the method, I get
prompted several times for a username/password--clearly it doesn't want to accept that user's authorization.

If anyone could explain why this is happening, and how I can
make it stop, that would be very helpful.

Thanks very much,
