HH:MM in 24hr format. When the minute values in the in the Start Time field are a lower value then the minutes in the End Time field the calculations work fine. Example: Start Time = 16:10 End Time = 17:55 Time = 01:45:00 Decimal Hr = 1.75 However, when the minutes in the Start Time field are a higher value then the minutes in the End Time field then the time and decimal value of the calculation fail. Start Time = 16:55 End Time = 17:50 Time = 01:5:00 Decimal Hr =1.#QNAN value Any help would be most appreciated.
