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:
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:
