I currently forecast # of orders for for a catalog based on it's life of 80
days. The forecast is broken out by expected orders per day. I also track
daily actual orders as they come in and compare them to my original forecast.
After 20 days, I would like to re-forecast the likely future orders based
upon my original forecast and the actual orders to date. Any suggestion?
Something from the Analysis Toolpak?

Thanks,
Tom
