Multiplies all the numbers in a range of cells in the whole workbook.
For example, you can use PRODUCT3D to return product of the numbers in a given range in the whole workbook. You just need to specify a range, and PRODUCT3D will go through the same range in all worksheets in the workbook and find out the answer for you.
PRODUCT3D is very similar to the PRODUCT function of Microsoft Excel. The main difference is that PRODUCT3D considers all worksheets, while the original PRODUCT function doesn't.
range_input - is the range in which the numbers you want to multiply.
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.
Cells that contain numbers, logical values, or text representations of numbers are counted; empty cells are ignored. Cells that contain error values or text that cannot be translated into numbers cause errors.
