i have a long array and i want so sum up pieces of it. So supposing it has x number of rows, want to sum every y number of rows, so sum the first y rows, sum the next y rows, etc. how do i do this? with a counter? i'm a little stuck, everything i code, the sums keep outputting zero....any help would be great. thank you so much.
