XL98: Setting RowSource Property Results in Run-Time Error

• Microsoft Excel 98 Macintosh Edition

SYMPTOMS

When you run a Visual Basic for Applications macro, you may receive the following error message:

   Run-time error '380:'
   Could not set the RowSource property. Invalid property value.

CAUSE

This error occurs when you attempt to programmatically set the RowSource property of a ListBox or ComboBox control on a UserForm.

The RowSource property is not available in Microsoft Excel 98 Macintosh Edition.

WORKAROUND

To work around this behavior, store the values in a worksheet, and then use a Visual Basic for Applications procedure to populate the control.
