Entering Functions with the AutoSum Feature
How AutoSum Works
Excel determines the range reference needed for the function being inserted by the
AutoSum feature by examining the layout of the data and choosing what seems to be the
most likely range. When you use the Sum button, Excel highlights the range it thinks you
want to use. For example, if you use the Sum button in a cell that is below a column of
numbers, Excel assumes that you want to summarize the values in the column. You can
change that range by typing a different range reference or selecting a different range.
Make sure to always verify the range AutoSum selected, especially when a
worksheet’s column or row titles contain numbers. AutoSum cannot differentiate between
numbers used as titles (such as years) and numbers used as data for the calculation.
