SYMPTOMS
When you are viewing a filtered list in Excel (on the Data menu, point to Filter, and then click to select AutoFilter) you may experience the following problems:
 * The AutoFilter list contains one entry that represents two different dates. When you select the entry, both dates appear in the filtered list.

-and-
 * When you click an item in the AutoFilter list, the selected item may be (Custom...) even though you did not previously create and select a Custom AutoFilter.



CAUSE
These problems may occur when the following conditions are true:


 * You are using the AutoFilter to filter a list that contains dates.

-and-
 * The dates have been formatted to use only two digits for years. For example, January 1, 1925 appears as 1/1/25.

-and-
 * The list contains dates in more than one century: for example, dates in the 20th and 21st centuries.

The problem occurs because the items in the AutoFilter list are displayed with the format that is applied to the cells in the list. If two dates are formatted so that they appear to be the same date, only one entry appears in the AutoFilter list for the dates.

For an example of this problem, please see the "More Information" section.



WORKAROUND
To work around this problem, format the dates in your list so that they use four digits for years. If the dates appear differently, each date appears separately in the AutoFilter list when you click it.



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



Example

  In Microsoft Excel, create a new workbook. In Sheet1, enter the following values and formulas:      A1: Date       B1: Year A2: 1/1/1925  B2: =YEAR(A2) A3: 1/1/2025  B3: =YEAR(A3) A4: 7/5/1998  B4: =YEAR(A4)  Select cell A1. On the Data menu, point to Filter, and then click to select AutoFilter.  Click the arrow in cell A1.

Note that both the 1/1/1925 and 1/1/2025 dates appear in the filtered list.</li> Click the arrow in cell A1; The (Custom...) item is selected in the list even though you have not previously selected it.</li> Click 7/5/98, and then click the arrow again. Note that the 7/5/98 item is selected in the list.</li> Click (All), and then select cells A2:A4.</li> On the Format menu, click Cells, and then on the Number tab, click Custom in the Category list.</li> In the Type box, type m/d/yyyy, and then click OK.</li> Click the arrow in cell A1.
