I have what seems to be a simple issue but I can't resolve it.
I have two columns. One will only ever be a value of 5,10,20,40,50,60,80,signed.
The other is just a currency value.
I've been looking into arrays to see if I can simplify this formula but I'm failing.
Right now, I need the formula to evaluate if the first column is a number and is greater than or equal to 40 but less than 80. If it is, it needs to multiply against the currency value next to it and return the total of the entire set of entries for which this is true.
Can someone help me formulate this as I just end up with a massive sum if. Surely there's a better way?
