Hi,

You could try this

=sumproduct((hour($A$1:$A$4)=hour(A10))*($B$1:$B$4 ))/sumproduct(1*(hour($A$1:$A$4)=hour(A10))

I need help coming up will a function that will average a range in one
column
based on if the hours match. Here is my set up.

-------A-------B
1.....09:21....12
2.....09:46....24
3.....09:57....17
4.....10:04....22

I need to average column B if column A's hour is the same as the hour in a
cell in another worksheet.
