Changing the order of text based on results

Hello. I've attached a spreadsheet. I want the order of the sentence to change based on the numbers and whether they are positive or negative. Below are more details and the spreadsheet has numbers. Thanks



"Total expense for September was 8 higher (lower) than prior year, driven by a higher (lower) claims expense and admin expense"


This might be hard to explain: For the second part (starting from "driven by", I would like the variable that explains more of the positive or negative variance (in the example, claims) to come first.

Here is a different example

Total expense for September was 6 lower than prior year, driven by a lower admin expense (claims is not included because it is higher)

Does this make sense?

Thanks
