These date time values represent clock in and clock out times into a system so subtracting the time in from the time out will give me the duration of time they were logged into the system.

These entries vary but each day starts with a date/time stamp of "System Login" and ends with a stamp of "System Shutdown". Kind of like a time clock situation. 3. I pull the start times with a VLOOKUP that looks for "System Login" and the stop times with a VLOOKUP that looks for "System Shutdown". If it doesn't find them, it enters "Null". 4. Now I've got columns C & D with 100 rows that say either "Null" or have a date/time stamp. 5. I now have to subtract the date/time values in column C from the matching date/time value in column D to get the duration of time worked for that particular day. The problem is that the start times and the stop times are in different rows, e.g. I might have the start time for 3/16/09 in C2 and the stop time in D6, the start time for 3/17/09 in C7 and the stop time in D10, and so on. Does anyone know of a formula I can enter in column E that will subtract the first date/time value in column C from the first date/time value in column D, the second date/time in column C from the second date/time in column D and so on down the line? Any help greatly appreciated. -- Regards Ashish Jain Sent from: New Delhi Delhi India. -- Thanks & Regards, Harmeet Singh --~--~---------~--~----~------------~-------~--~----~ ------------------------------------------------------------------------------------- Some important links for excel users: 1.
