XL97: Cannot Use Custom Function with Data Validation

• Microsoft Excel 97 for Windows

SYMPTOMS

When you use custom criteria with data validation and attempt to type a custom function in the Formula box in the Data Validation dialog box, the following message appears:

   A named range you specified cannot be found.

CAUSE

This behavior occurs when the following conditions are met:

• You click Validation on the Data menu, and then click the Settings tab.

  -and-

• You click Custom in the Allow box.

  -and-

• You type a custom function in the Formula box.

WORKAROUND

To work around this behavior, type the custom function in a cell on the worksheet, and then type a formula that refers to this cell in the Formula box. For example, type the custom function in cell A1, and then type "=A1" (without the quotation marks) in the Formula box in the Data Validation dialog box.

STATUS

This behavior is by design of Microsoft Excel 97 for Windows.

MORE INFORMATION

The Custom data validation criteria type allows you to type a formula, use an expression, or refer to a calculation in another cell to determine a valid entry. When you type a formula, the formula must evaluate to True or False.
