Putting a formula in place one time for the entire spreadsheet

[jacob]

I would like to add the number displayed in every 15th cell in the B
column (starting with B20) and display those results in B5. Instead of
using
=(B20+B35+B50...)
is there a quicker formula I can use?


ALSO:

Is there a workday formula I can use to put the first workday of any
given month in a target cell, and then every 15th cell in the same row,
put the following day?

So: A1= 5/2/05
A16= 5/3/05
and so on...

Thanks guys!!!!!!!!!!!!!

Every 15th cell all the way to the bottom of the worksheet???

=SUMPRODUCT((MOD(ROW(B15:B65536),15)=0)*(B15:B65536))

Hi,

I used your formula, but it gives a #VALUE in B5 instead of the total.
Any ideas?

Technically, I want the formula to add every 15th cell, starting with
B15 and ending with cell B350. I modified the above formula to end in
350, but I still get a #VALUE displayed. Any ideas?

Thanks again

It works for me. Perhaps you have text in some of the cells?

No text. (there are some blanks, some of the B column cells have not
been filled out with a number yet. Those cells contain a formula, but
no value)Would you mind me sending you the document? i have to be doing
something wrong.

Sorry, I'm on the road and am having trouble downloading files. I will
definitely look at it over the weekend.
