query problem

[peljo via AccessMonster.com]

I want to make a query with two conditions : to include all the orders having
orders.Audit = > True and also all the orders where orders.Suborder = true.
I want to exclude the orders that have no criteria as Audit = True or
Suborder = True.
I cannot do it, since in the query I have built there are also orders which
have neither Audit = True or Suborder = True
How can I exclude those last order from the query? I did try to add in the
where clause orders.suborder = True but the query does not give the right
results

SELECT orders.orderid, orders.audit, orders.SubOrder
FROM orders INNER JOIN [order details] ON orders.orderid = [order details].
OrderID
GROUP BY orders.orderid, orders.audit, orders.SubOrder
HAVING (((orders.orderid)>=(SELECT Max(orders.orderid) FROM orders WHERE
orders.Audit =True)));

In our database we begin calculating from the orderid that has Audit = true.
There is only one order with Audit = True, but after this order there are
many orders that have Suborder = True and a lot of orders that have no
restrictions.My first task is to calclate the quantities from all the orders
where Audit => true or Suborder = true. I will be very grateful for any help
in this difficult assignment.
I can send an example if needed.
