Given: an events table and a clients_payments_received_table, using Access 2003

I would like to Left (outer) JOIN events to the following result

SELECT clients_payments_received.clpr_eventid, SUM(clients_payments_received.clpr_amount) AS total_payments
FROM clients_payments_received
GROUP BY  clients_payments_received.clpr_eventid

Would like to do this in one SQL statement.

Any ideas?

you might try this:
SELECT cp.clpr_eventid, SUM(cp.clpr_amount) AS total_payments , e.event_name
FROM clients_payments_received cp
LEFT OUTER JOIN events e
  ON ( e.eventid = cp.clpr_eventid )
GROUP BY  cp.clpr_eventid, e.event_name

Uggg. Not what I was looking for. (My Fault) The query works...but it doesn't return the results that I want.

I am looking for all results from the events table with a ZERO value for events that don't have any payments.

no problem, just reverse the join:
SELECT e.eventid, e.event_name, SUM(cp.clpr_amount) AS total_payments 
FROM events e
LEFT OUTER JOIN clients_payments_received cp 
  ON ( e.eventid = cp.clpr_eventid )
GROUP BY e.eventid, e.event_name
