Create Budget - from History

I am having a problem with creating a Budget from History. It is making all entries for zero dollars. I entered the history beginning date as 01/01/01 and I do have entries for that year and budget beginning date as 01/01/02 and the no of periods as 12 and the period length as month. I am kind of stuck with this. Any help would be appreciated. Thanks, anu N.Anu
