hmm, I have no idea what that one is, or if it's relevant.

hmm. ZPatterns is a rather complex system which I've never used.
If your application uses it, i'm afraid I can't help with that.

everything else looks like standard stuff.

ZCatalog is described here:
http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/SearchingZCatalog.stx

There is evidently at least one instance of ZCatalog catalog in your 
zope site somewhere, named Catalog, because it's referred to by 
that name in the External Method you posted.  So search for things 
with the id "Catalog".

see above.

yes, it was an example. I don't know where this Catalog is in your site.
It's evidently in or above the folder that contains the External Method
you posted.

I copied that from the external method you posted!

something like that. I can't be more specific because I don't
have your application in front of me.

Hmmm.  I've actually given a lot more help than I planned on already.
I don't mind helping but I am starting to wonder why you are being
paid for this and I am not :)
