you assume you have a list of 100 cells in a column, and you determine that
you want to sum the values in three sections of this list. The start and

to sum the values in these three sections?

Thanks in advance for your help!

Hi Tom,

Let's say your value cells are in C1:C100. I'm assuming columns A and B
are "start" and "stop" row numbers to sum. Then this works:

=SUM(OFFSET(C1,A1-1,0,B1-A1+1))+SUM(OFFSET(C1,A2-1,0,B2-A2+1))+SUM(OFFSET(C1,A3-1,0,B3-A3+1))

There are probably more elegant ways though.
