Grace -

Because you are searching for a time range (i.e. 13:00 through 13:59), you will need to use the SUMIFS() function. It allows you to search for multiple criteria.


SUM_RANGE are the cells that contain the data that should be added, in the case of your sample that would be column C.
CRITERIA_RANGE1 is the cells that contain the hours. In this case, column B.
CRITERIA1 is where we begin the hourly range. Since we're trying to get anything within the 1 o'clock hour, we choose something that means "1:00 or anything after" -- ">=13:00"

If we leave it at this criteria, we'll get everything from 1:00 on. We need to put an end on the range.
CRITERIA2 should be for "anything before 2:00" -- "<=13:59"

The complete function for the 1 o'clock hour is:

Just change the time in the function to get the other hours totals. Hope this helps - Andrea
