I just downloaded the db again from my downloads and the orders table does not have them.
CREATE TABLE orders (
OrderID int(11) NOT NULL auto_increment primary key,
OrderReferenceID varchar(50) default NULL,
OrderUserID int(11) default NULL,
OrderShipping double default NULL,
OrderTax double default NULL,
OrderTotal double default NULL,
OrderDate datetime default NULL,
OrderStatus smallint(6) default NULL
BTW, i have found that when using a table called 'users' with DW, you can run into non-functioning extensions. Apparently it is a reserved word with some applications... like Adobe Developer's Toolbox...
