For example, use the following code: If there are one or more chart sheets in the workbook, they are deleted. If there are no chart sheets in the workbook, the command to delete the chart sheets is not executed. This prevents the macro from deleting any of the worksheets.

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem no longer occurs in Microsoft Excel 2000.

Note that this problem does not occur in earlier versions of Microsoft Excel. In earlier versions of Microsoft Excel, if the workbook does not contain any chart sheets, you receive the following error message: Also, note that charts that are embedded in worksheets do not count as chart sheets. If the workbook contains embedded charts but not chart sheets, the Charts.Delete command removes one or more worksheets from the workbook.
