A difference of 10 days in Access SQL

I want to show how many orders have been shipped 10 days before the required date in Access SQL, but I can’t seem to get the syntax right.

SELECT COUNT(*)
FROM Orders
WHERE DATEDIFF(day,RequiredDate,ShippedDate)=10;

​x
 
SELECT COUNT(*)FROM OrdersWHERE DATEDIFF(day,RequiredDate,ShippedDate)=10;​

Answer

SELECT Count(*)
FROM Orders
WHERE (((DateDiff("d",[Orders].[RequiredDate],[Orders].[ShippedDate]))=10));

 
SELECT Count(*)FROM OrdersWHERE (((DateDiff("d",[Orders].[RequiredDate],[Orders].[ShippedDate]))=10));​
