Hi all

I have this sample data from which I have to calculate the ActualTime taken.
Which is calculated by the formula : ActualTime=TimeTaken-Total Break
For each Time Taken, there may be more than one break times which come in
the column Total Break.

Example:
For first row Time taken = End Time - Start Time which is 00:00:23
Actual Time = [Time Taken - Total Breaks between Start Time and End Time]
i.e. X = 00:00:23 - (0:00:03+0:00:04+0:00:03)
X = 00:00:23-(0:00:10)
X= 00:00:10
Similarly Y = 00:00:45-(0:00:05+0:00:05+0:00:03+0:00:04)
Y=00:00:28
I am looking for any formula or macro which can calculate X, Y taking into
consideration the start time and end time range. For any break if the break
start and break end time fall into any start time and end time range, the
break should be deducted from time taken.

Waiting for help...

The code below assumes the Test Start is at location A2 and the Test En
is at B2 and the Time Taken is in C2.

Set BreakStart = Range("E$2:E$9")
Set BreakEnd = Range("F$2:F$9")
Set TotalBreak = Range("G$2:G$9")

ActualTime = C2 - sumproduct(--(BreakStart >= A2),--(BreakEnd =
B2),BotalBreak)


This is the simple case where the break times always fall between th
Start Time and End Time.


The problem gets more complicated if you have the following


Start Time End Time TimeTaken
14:33:49 14:34:12 00:00:23


ActualTime Break Start Break End Total Break
14:34:00 14:35:00 1:00


The above case the break is at the end of the test time and continue
past the end of the test
