Is Group No unique? It seems strange that the Pkey of the Customers table isn't just CustomerID. Sounds like a table design issue.

I have to join on the CustomerID and the [Group No] because some CustomerID's have multiple [Group No] but not all the groups have payments. The form is for payment adjustments so only the groups that have payments should appear on the form.

That shouldn't happen. I've seen this in Reports because the report engine tries to "optimize" the Record Source based on grouping specs, but I can't remember seeing this happen in a combo box. Try changing the Row Source to this SQL:
SELECT tblCustomersMain.[Group No], tblCustomersMain.[Account Name], tblCustomersMain.[Contact First Name], tblCustomersMain.CustomerID
FROM tblCustomersMain
WHERE (((tblCustomersMain.[Excluded from Payments])=False)) AND
tblCustomersMain.CustomerID & tblCustomersMain.[Group No] IN
(SELECT [Customer ID] & [Group No] FROM tblExpectedTotals)
ORDER BY tblCustomersMain.[Account Name], tblCustomersMain.[Group No];
That's a bit of a kludge because you're joining on two fields, but it should work OK depending on the data types of CustomerID and Group No. Why are you having to join on two fields?

Greetings All,
The following SQL is a saved query that is the row source for a combo box on a form:
SELECT DISTINCT tblCustomersMain.[Group No], tblCustomersMain.[Account Name], tblCustomersMain.[Contact First Name], tblCustomersMain.CustomerID
FROM tblCustomersMain INNER JOIN tblExpectedTotals ON (tblCustomersMain.CustomerID = tblExpectedTotals.[Customer ID]) AND (tblCustomersMain.[Group No] = tblExpectedTotals.[Group No])
WHERE (((tblCustomersMain.[Excluded from Payments])=False))
ORDER BY tblCustomersMain.[Account Name], tblCustomersMain.[Group No];
When I run the query from the query designer, I get the expected result of only the rows from tblCustomersMain that have a related row in tblExpectedTotals, a total of 294 rows.
However, as the rows source for the combo box, it is returning Group No from tblCustomersMain that do not have a related row in tblExpectedTotals, a total of 330 rows.
Am I missing something? This is Access 2007 on Windows 7 Enterprise.
