David, I think you have the numbers flipped there. The first field listed should be START DATE for the calculation, and the second field should be the END DATE for the calculation. Otherwise, you'll get a negative number. DATEDIFF(date1,date2) OR DATEDIFF(Entry Date,Actual Completion Date) That calculation does full calendar days. If you want closer to business days, I suggest using WEEKDAYDIFF. The same principle applies. WEEKDAYDIFF(date1,date2) OR WEEKDAYDIFF(Entry Date,Actual Completion Date) - You may also be able to use a calculated text mode column, but I'm still learning how to do those effectively. Maybe someone else can help with that. Vincent Goodwin The Capital Group Companies
