Hi.
Thanks for the solution but it does not quite work, This is data for options on ventilation programme and capacity, D21:D23 are 0 if the option to use if the types are not used, If they are "0" then the D17 is the number of people reduced by 30% so the data in D17 is formatted at percentage, hope that makes sense. The end part of the formula works on its own!
Thank you for the time.

The layout doesn't match your formula. It also lacks column and row headers.
And if every value is 0 then subtracting and multiplying does not change anything.
Please provide a workbook with a meaningful explanation.
