=if(I12N12,N12-D12,I12-D12)

I assume you put J12 there because that is where you put this formula

Thanks, but that just returns "FALSE" and doesn't do the calculations.

Anyone know how to write a formula for this?

IF(I12N12) then J12=(N12-D12) but if(I12<N12) then J12=(I12-D12)

where I12 is derived from another formula (=SUMC12+M12) and C12, M12
and N12
are simply input numbers.
