I'm new with this, and run into following issue:
I copied my real dataset into column A and B and also added an extra number on the bottom.
Then I change this part of the formula (2 parts) to the last cell number in my dataset. but then I get following error message:

"You cannot change part of an array"

how can I solve this?
