I moved my TablesSheet to a new workbook. Excel took care of the links except for the combo boxes. The ComboBoxes are still in the Estimate Workbook and the ListFillRange for each ComboBox is on the TablesSheet in the new WorkBook. Now the ComboBox drop down menus are blank. Is there a way to link the ComboBox on the Estimate Workbook to the ListFillRange in the Tables WorkBook? Excel 2003 SP3. Thanks again for your help.
