One way:

=E9*F9*MAX(1-$G$24,70%)


or, equivalently

=E9*F9*(1-MIN($G$24,30%))

I am trying to cap a cell that I use for discounts.
eg the cell could read 35%, but I only want a max of 30% on some products
I am using a cell to input a discount into quotations, this cell is then
used to calculate sums further below eg
g24 = 40%
and I use =(E9*F9)*(1-$G$24) later to get my total BUT I want to be able to
cap some lines with a lower discount eg some products can have up to 40% ,but
others can only go up to 30%.
=MIN(SUM(A1:A10),100) This sum works if the cell is formatted as a general
number, but not if it is formatted as a percentage.
