Remarks

* This function includes hidden cells.
* For an illustrated example refer to the page under Advanced Functions.
* Arguments that are numbers are included.
* Arguments that are zero are included.
* Arguments that are dates are included.
* Arguments that are logical values are excluded.
* Arguments that are text are excluded.
* If any cell references are empty, then these are excluded. (Row 5).
* If any cell references contain an error, then that error is returned.
* You can have a maximum of 255 arguments.
* You can use this function to get the number of entries in a number field in a range (or array) of numbers.
* You can use the COUNTA function to include logical values and text.
* You can use the COUNTBLANK function to return the number of blank cells.
* You can use the COUNTIFS function to satisfy multiple conditions.
* You can use the COUNTVISIBLE - User Defined Function to exclude hidden cells.
* You can use the AGGREGATE function to exclude hidden cells.
* This is similar to the AVERAGE function.
