I'm having issues how to design this form. I have form with (Date, ProductID, ProductName, ProductPrice and LastNumebrSold) This information is enter daily. For each day I like to see the previous days data all in one form and update only the [LastNumberSold] and also enter any new product that was not in the day before and at the end I want to run report to give me the diffrent between the two day's LastNumberSold. I tried Dlookup but I'm afraid I eill mis product that was sold out before the new day's data. Any help with help. Thanks
