Thanks Lobo,
When I eliminate line 679 (I'm not really a module builder so I'm afraid I may be doing it wrong)
WHERE contact_type LIKE 'Individual'
...the site throws a nonrecoverable error.

However, if I change it to:
WHERE contact_type LIKE 'Organization'
...it outputs just the orgs

or:
WHERE contact_type IS NOT NULL
...I get all contact types.

Look who's making modules change!
Anyway, thanks for the tip and the quick response. I'll keep plugging.
