Conditional Functions

[Guest]

I have data in 2 columns that I want to work with. In one column (O) is a
percentage that sometimes equals 0. In the other (P) is a percentage that
never equals 0. Now in the third column (Q), I have the function =(P2-O2)/O2,
but sometimes, when O=0%, the function doesn't work. So I changed it to say
=IF(OR(O2=0%,(P2-O2)/O2>200%),200%,(P2-O2)/O2). I never want the Q column to
be more than 200%. It works for numbers that quotient to more than 200%, but
for functions where O=0%, it says #DIV/0!, where it should just say 200%, as
I've instructed it.
What should I do?

The result #DIV/0! appears to be from the "OR" part of the formula.
OR(O2=0%,(P2-O2)/O2>200%

I.e. in evaluating the second part of the OR it gets the fault
,........

You could change the IF formula to a triple nested IF

=IF(O2=0%,200%,IF((P2-O2)/O2>200%,200%,(P2-O2)/O2))
