Following a previous post from Hui, I was able to add a module and get the formula below to work. But how can I tweak it if the formating has been applied to the date column (e.g. column A) but I need to sum the cash column (e.g. column C)?
=ColorFunction($K$22,$M$1:$M$20,TRUE)
=ColorFunction($K$22,$M$1:$M$20,TRUE)
