Re: Protecting Cells In Shared Workbook you can simply add a workbook change event. VB: Private Sub Workbook_SheetSelectionChange(ByVal Sh As Object, ByVal Target As Range) Cells.Select Selection.Font.ColorIndex = 0 End Sub. this will automatically change the font colors back to black in all cells on active sheet.
You can protect cells (or whole rows or columns) by highlighting the cells (i.e. data input cells) you DON'T want to protect then click on Format->Cells->Protection tab. Uncheck the Locked box. Now protect your worksheet and/or workbooks with a password.
