Dmax problem

I have table with this fields:
Article_ID, Date_In, Q_In, Date_Out, Q_Out

I need query (report) that will show only
the last Date_In and the last Date_Out
for each Article_ID.

I think the solution is in the filter with
Dmax function.I find out how to use
this function in form (using VBA) but I just
don't get it how this works in query.

The records looks like this:
Article_ID,Date_In, Q_In,Date_Out,Q_Out

cu001 01/05/05 55 0 0
cu002 02/05/05 30 0 0
cu001 0 0 05/05/05 20
cu002 0 0 08/05/05 10

Any help will do.Thanks

I find out the solution that will give me the last Date_IN for every Article_ID. So my suggestion is to split this problem in two queries (one for Date_IN and one for Date_out) and then insert it new table . Maybe there is a better solution but this one worked for me (the amount of quantities is not important for me and the query gives the sum )

SELECT DISTINCTROW TableName.Article_ID, Max(TableName.Date_IN) AS MaxOfDate_IN, Sum(TableName.Q_IN) AS [Sum Of Q_IN]
FROM Tablename
GROUP BY TableName.Article_ID;
