# Error Alert

Define the error message that is displayed when invalid data is entered in a cell.

You can also start a macro with an error message. A sample macro is provided at the end of this page.

To access this command...

Choose Data - Validity - Error Alert tab.

## Show error message when invalid values are entered.

Displays the error message that you enter in the Contents area when invalid data is entered in a cell. If enabled, the message is displayed to prevent an invalid entry.

In both cases, if you select "Stop", the invalid entry is deleted and the previous value is reentered in the cell. The same applies if you close the "Warning" and "Information" dialogues by clicking the Cancel button. If you close the dialogues with the OK button, the invalid entry is not deleted.
