Hi Whitney,

Following formulas should work on your sample data. You need to make one
criteria greater than () and the next one less than or equal to (<=)
otherwise a time like 6:15:00 would get included in the 6:00:00 to 6:15:00
and also 6:15:00 to 6:30:00. Based on this, you might have to adjust the
formulas to return the required values. You might want to make the first
criteria equal to or greater (=) and the second one less than (<)

Examples assuming:
Dates are in column A
Times in column B
Agents in column C

6:00 to 6:15 =SUMIFS(C2:C39,B2:B39,"6:00:00",B2:B39,"<=6:15:00 ")

6:15 to 6:30 =SUMIFS(C2:C39,B2:B39,"6:15:00",B2:B39,"<=6:30:00 ")

6:30 to 6:45 =SUMIFS(C2:C39,B2:B39,"6:30:00",B2:B39,"<=6:45:00 ")

6:45 to 7:00 =SUMIFS(C2:C39,B2:B39,"6:45:00",B2:B39,"<=7:00:00 ")

7:00 to 7:15 =SUMIFS(C2:C39,B2:B39,"7:00:00",B2:B39,"<=7:15:00 ")


Feel free to get back to me if this does not answer your question as you
would like.

Regards,

Ossiemac

Can anyone help with a lookup formula that will look at the cell closes to
6:00, 6:15, 6:30, 6:45, 7:00, etc. and tell me what the number of agents
we're (cell to the right) in each interval? There is no pattern, so the
lookup value will not always be in the same cell location each day.
