Adds all the numbers
in a range of cells in the whole workbook.

For example, you
can use SUM3D to return the sum of the numbers in a given range in the whole
workbook. You just need to specify a range, and SUM3D will go through the same
range in all worksheets in the workbook and find out the answer for you.

SUM3D is very
similar to the SUM function of Microsoft Excel. The main difference is that
SUM3D considers all worksheets, while the original SUM function doesn't.

Syntax

SUM3D(range_input,
include_current)

range_input
- is the range for which you want to determine the total value or sum.

include_current
- Optional. Boolean argument , either TRUE or FALSE. Decides whether the current
worksheet is included in the function's consideration. TRUE means the current
worksheet will be considered, and vice versa.

Range(s) that
include error values or text that cannot be translated into numbers cause errors.
