SYMPTOMS
The COUNTIF function may return an incorrect, smaller result when counting blank cells.



CAUSE
This problem occurs when the following conditions are true:


 * The COUNTIF function references a criteria range with blank cells at the right or bottom of the range.

-and-


 * The function uses "" as the criteria.

-and-


 * The "used range" of the worksheet, as defined by the last column and last row with data, does not include the blank area of the referred-to criteria range.



WORKAROUND
To work around this problem, type some numbers or text to the right of and below any ranges used in such formulas. Excel then sees the rectangle starting with A1 to the "last cell," as defined by the column and row of that entry, as being used or "dirtied," and the formulas will work as expected.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
If the COUNTIF function returns an incorrect smaller value due to this problem, and the workaround is applied, you must cause Excel to completely recalculate before the functions can work correctly. To do this, re-enter the formula or press COMMAND+SHIFT+F9. If data is deleted to create a smaller "used range," you must save the workbook to cause Excel to recognize that there is a new "used range," and then recalculate the workbook.
