Totalling values in column X for all rows with identical values in column Y

[mahoopesinDE]

I want my formula in F10 to return the sum of the values in column D (hours worked) by each volunteer (identical names in column A).  I get a circular reference error.  Can anyone show me where I'm going wrong?   Thanks to all!

@mahoopesinDE -

Are you trying to achieve something like:

F2 = SUMIFS($D$2:$D$13,$A$2:$A$13,A2)

Copy that formula down.

Otherwise you could do something like:

Where

I2 = SUMIFS($D$2:$D$13,$A$2:$A$13,H2)

Copy that formula down.

To identify the cell where the Circular Reference occurred:

1. Click on Formulas tab
2. In the Formula Auditing group,click on the dropdown of Error Checking
3. Click on Circular Reference and the cell that contains circular reference.
4. Then adjust the cell reference as appropriate

As variant, if data sorted by names and show totals against last record with each name

=IF( A2=A3,"",SUMIF(A:A,A2,D:D))

or simply pivot the range
