If your queries must match _all_ of your input variables, you are in the

there is an AND between each of them in the right places. This

If you want to use the index, you cannot put the column through any
function. You have to compare the column value, as is, to constants. For
example,
SELECT SUM(OrderSubTotal) FROM tblOrders
WHERE ShipDate BETWEEN '2004-09-01' AND '2004-09-30';
should do what you want.
