Access 97 - sorting numbers

i have a table listing customer names and addresses, along with unique customer id numbers.

I have a simple query to identify the duplicates, and this lists customer names and customer numbers.

What I now want is a table with 2 columns of customer numbers - one for the original (lowest) customer number, and one for the duplicate. Any easy way to do this? all ideas welcome!

got a fix from a friend in the meantime:
SELECT Dupstha2_1.FNAME, Dupstha2_1.LNAME, Dupstha2_1.[Cust No], Dupstha2_2.[Cust No]
FROM Dupstha2 AS Dupstha2_1, Dupstha2 AS Dupstha2_2
WHERE Dupstha2_1.[Cust No] < [Dupstha2_2].[Cust No]
AND Dupstha2_1.FirstNAME = Dupstha2_2.FirstNAME
AND Dupstha2_1.LastNAME = Dupstha2_2.LastNAME
AND Dupstha2_1.STREET = Dupstha2_2.STREET;

Basically what is does is that it joins the Dupstha2 table with itself on the FNAME column and the STREET column. The Dupstha2_1.[Cust No] < [Dupstha2_2].[Cust No] makes sure that the two [Cust No] combinations is only shown once.
