XL98: Cannot Use Custom Function with Data Validation (186056)

The information in this article applies to:

Microsoft Excel 98 Macintosh Edition

This article was previously published under Q186056

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.

By design, 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 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:
