To get the first set:

=SUMPRODUCT(I1:I1000,--(MOD(ROW(I1:I1000),14)=1))

To get the second set:

=SUMPRODUCT(I1:I1000,--(MOD(ROW(I1:I1000),14)=2))

I need to be able to add up the value of a cell in every 14th row.
The spreadsheet contains the results from a daily report (30 days
worth). Each report is 14 rows. I need to add the results of one line
for each report.
In other words I need to add cells I1, I15, I29, I43, I57; and then I2,
I16, 130, I44, I58, etc.

Can someone provide feedback?

Thanks
