XL97: Cannot Use Custom Function with Data Validation

ID: Q160523

The information in this article applies to:
  • 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.


When you use custom criteria for data validation, Microsoft Excel accepts only a built-in formula or a defined name 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.


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. For additional information about data validation, please see the following article in the Microsoft Knowledge Base:
