I need to perform a calculation and have it adjust in the next cell based on the previous cell

This is the formula I am using:  =IF($B$19+$C$30<2042,B19+$C$30,0), the problem is when I copy to the next cell it gives me the value 12 because the returned value is 0 + 12 = 12, but the value should be 0.  See sample

(see attached spreadsheet)

It looks like you also need to make B19 absolute, ie turn it in $B$19 so it maintains the reference to the year in B19:


although I am not sure the significance of copying the same formula/result across the cells ?!?

And perhaps you need to remove the $ from before the 30 in $C$30 so that you can copy down and get reference to C31, C32, etc...

Looks like you are wanting to increment the year value in row 30 by the number of years in C30 up to a max year of 2042 which I take it you are getting from start year (B19) plus expected life (B22).

If so try this:


in F30 and then copy across as far as required.

Copying across are years where I have the 1 2 3 4 5 6 across
See updated sheet and formula change
Problem occurs in column #4, 5, 6, etc.  The values should appear as 0 but because the result is less than 2042 it adds the 12 to the 0 giving the results of 12 24 36 48.  I need it to calculate if the result is 0 in the previous cell then it should not sum the requency routine maintenance values thus resulting in a 0
Starting in G30, try:


copied across.

Did you try my suggestion, this would put zero in columns if calculated beyond 2042?
