The information in this article applies to:
  • Microsoft Excel 97 for Windows
  • Microsoft Excel for Windows 95, versions 7.0, 7.0a
  • Microsoft Excel for Windows, versions 3.0, 4.0, 5.0, 5.0c

SUMMARY

When you use any of the worksheet functions in the Microsoft products listed at the beginning of this article, and you have a range argument that includes either hidden rows or columns, the cells in these hidden areas are still used by the function. For example, if you have the following in a worksheet 

   A1: 1
   A2: 1
   A3: 1
   A4: =SUM(A1:A3)
the SUM function in cell A4 returns a value of 3. If you then hide Row 2, the SUM function still returns a value of 3.

MORE INFORMATION

If you would like to sum only the Odd or the Even rows in a range, instead of trying to hide rows, which does not work in this case, you can use the following formulas.

Odd Rows

   =SUM(IF(MOD(ROW(A1:A3),2)=1,A1:A3,0))
If you enter this as an array formula in cell A4 in the above example, it returns a value of 2.

NOTE: To enter a formula as an array formula in Microsoft Excel for Windows, press CTRL+SHIFT+ENTER. In Microsoft Excel for the Macintosh, press COMMAND+RETURN.

Even Rows

   =SUM(IF(MOD(ROW(A1:A3),2)=0,A1:A3,0))
If you enter this as an array formula in cell A4 in the above example, it returns a value of 1.

NOTE: If you still want to hide rows for the above example, the two functions given will still work as outlined.
