I've got a very standard collect.cfg file with two AZCompactList entries
like this:

classify AZCompactList -metadata Subject -mingroup 1
classify AZCompactList -metadata Contributor -mingroup 1 -buttonname
People

which should process GS archive files with these metadata elements:-

<Metadata name="Contributor">Bannister, Mrs., actress (performer)
</Metadata>
<Metadata name="Contributor">Harris, Mr., choreographer
(production personnel)</Metadata>
<Metadata name="Subject">Theater -- England -- London -- History --
18th century</Metadata>
<Metadata name="Subject">Printed ephemera</Metadata>
<Metadata name="Subject">Playbills</Metadata>

etc etc.

The collect.cfg is in fact exactly the same as those used on other
collections I have, with just the collection name changed. The archive
files follow exactly the format of those in the other collections.

The problem is:-no subject and people buttons turn up for this collection,
and no searching of these indexes is possible. There's no such problem with
the other collection using the same collect.cfg files.

I must be doing something blindingly obviously wrong here, but can't see
what it is. Any pointers?

Many thanks
Richard
