Thanks! Worked like a charm. By the way, if N1 is never going to be less
than zero, do i have to have that first formula with "unknown"?

I could really use some help. I have only a basic knowledge of Excell
formulas, and I am trying to do the following calculation in a cell using
comparisons of other cells.

N1, and all the T cells are other cells that i am using for this formula

If N1=0, then zero
If N10, and T1-T2=T3*T4, then T3*T4
If N10 and T1-T2<T3*T4, then T1-T2

I hope this makes sense. Thanks in advance to anyone who can help me.
Thank you!


=IF(N1<0,"unknown",IF(N1=0,0,IF((T1-T2)=(T3*T4),T3*T4,T1-T2)))
