trying to save some time

[Brown]

Good afternoon,

I am trying to add a string of 60 numbers, all in the same column, but they are all 11 cells apart. What is the easiest way to do the formula =sum( )?
is it best to click on every cell, type all of the cell names, or is there a shortcut you guys know that will help me get all of the cell numbers in the formula quickly?

I hope this is making since.

thanks
Brown

i will right now, thanks

ok so here is the formula i used
=SUMPRODUCT(--(P3:P711),--(MOD(ROW(P3:P711),12)=3))

and i am getting the #value show up in the cell

i used your formula and changed the p710 to p711, and changed the 11 to a 12
