SELECT And Dates Question

My table contains three records as an example

item boxes quantity date
CH 20 16 10/09/2007
CH 10 20 11/09/2007
CH 15 16 12/09/2007

using the request:

SELECT item, sum(boxes), quantity FROM transactions WHERE (item = 'CH' AND date_recvd BETWEEN '09-09-2007' AND '12-09-2007') GROUP BY item, quantity

I get:

CH 35 16
CH 20 10

but if I change my date parameters to:

SELECT item, sum(boxes), quantity FROM transactions WHERE (item = 'CH' AND date_recvd BETWEEN '09-09-2007' AND '10-09-2007') GROUP BY item, quantity

I still get:

CH 35 16
CH 20 10


My query syntax is obviously incorrect. What should it be please?
