Putting a different Formula in every 7th row

[bite_tony]

Hi,
I have a spread sheet where:
6B-6C=6D
Then 7B-7C+6D=7D and so on and so fourth
(see attatchment)

I would like to put a different formula in the 7th row (12D)

Is this possible at all?
Thanks for your help

I assume you mean for dragging purposes - use the method I suggested in your other thread.
