On the startup form of the attached mdbs, select "Portata Povo" then, on the calendar, select 1 September 2009, click on the button that says, "set start date", on the calendar select 30 September 2009 and click on the button that says, "set end date" and click the Chart button. Why does the pivot chart show in one file but not in the other one? Might be useful to point out the table in the one that doesn't work has been created from data originally in SQL Server.
