Help With Outer Join Query In Acess 2003

hello,

I have query , which has got 2 outer joins. The query is:

SELECT A.Project_ID, A.Title, A.comm1 AS Comments, A.Partner AS PM, A.Staff_Assigned AS TL, A.Contact_Name AS FL, A.MD, A.Status, A.Project_Type,
ISNULL(B.Delivered_Date, B.Delivery_Date) AS Start_Date, ISNULL(C.Delivered_Date, C.Delivery_Date) AS End_Date
FROM dbo.PROJECT A LEFT OUTER JOIN
dbo.PROJDATE B ON A.Project_ID = B.Project_ID AND B.Date_Type = "Start Date" LEFT OUTER JOIN
dbo.PROJDATE C ON A.Project_ID = C.Project_ID AND C.Date_Type = "End Date"

Can anybody help me out the error with this. I get an error : at dbo.PROJDATE B ON A.Project_ID = B.Project_ID AND B.Date_Type = "Start Date" .

Do I need to use any parantheris or change anthing.
