An application error has occurred and an application log is being generated.

After displaying the error messages, Microsoft Excel 97 for Windows quits.

CAUSE

• You are using the xlLocationAsObject constant for the Where argument of the Location method. -and-

To prevent this problem with your macro, use a valid worksheet name for the Name argument of the Location method.
