I have this sheet:
In the column "E" I need the same operation as ARRAYFORMULA in column C and D.
In column E I need to make a simple SUM and this is what does not work.
How do I resolve?
Can I use this magic formula:
but with SUM?
I need to use this magic formula which repeat for every rows the formula i choose, but I need repeat in each rows a formula with SUM that now doesn't work. How to?
