The following example creates a user-defined function that sums values based on a custom number format.

Preparing Sample Data

1. Create a new workbook and type the following data: 

      A1: 100
      A2: 5
      A3: 100
      A4: 5
      A5: 100
2. Select cells A1, A3, and A5. To do this, press and hold down CTRL, and 
   then click cells A1, A3, and A5.
3. On the Format menu, click Cells. Click the Number tab.

4. In the Category list, click Custom. In the Type box, type "F"0, and then 

   click OK.
NOTE: You can use different custom number formats with this example.

Creating the Function in Microsoft Excel 97 and 98

1. Press ALT+F11 to start the Visual Basic Editor.

2. On the Insert menu, click Module.

3. In the module sheet, type the following code: 

      Function SumFormat(CellRange)

         ' Loop through each cell in the range that is passed to this
         ' function.
         For Each Item In CellRange

            ' Check to see if the cell is formatted as "F"0.
            ' The additional quotation marks are necessary to look for
            ' actual quotation marks in the format string.
            If Item.NumberFormat = """F""0" Then

               ' Add the cell value to the variable total.
               total = total + Item.Value

            End If

         Next Item

         ' Set the results of total equal to the function name.
         SumFormat = total

      End Function
4. On the File menu, click "Close and Return to Microsoft Excel."

5. Select cell A7.

6. Type "=SumFormat(A1:A5)" (without the quotation marks), and then press 

   ENTER.

   Cell A7 contains the value 300 because cells A2 and A4 are not formatted
   with the custom number format of "F"0.

Creating the Function in Microsoft Excel 5.0 and 7.0

1. On the Insert menu, point to Macro, and then click Module.

2. In the module sheet, type the following code: 

      Function SumFormat(CellRange)

         ' Loop through each cell in the range that is passed to this
         ' function.
         For Each Item In CellRange

            ' Check to see if the cell is formatted as "F"0.
            ' The additional quotation marks are necessary to look for
            ' actual quotation marks in the format string.
            If Item.NumberFormat = """F""0" Then

               ' Add the cell value to the variable total.
               total = total + Item.Value

            End If

         Next Item

         ' Set the results of total equal to the function name.
         SumFormat = total

      End Function
3. Click Sheet1.

4. Select cell A7.

5. Type "=SumFormat(A1:A5)" (without the quotation marks), and then press 

   ENTER.

   Cell A7 contains the value 300 because cells A2 and A4 are not formatted
   with the custom number format of "F"0.
