Hi Wim
Private Sub Workbook_Open()
Worksheets("Sheet1").EnableAutoFilter = True
Worksheets("Sheet1").Protect UserInterfaceOnly:=True
End Sub
Right click on the Excel icon next to File in the menubar
choose view code
paste the code
Alt-Q to go back to Excel
This runs every time the workbook opens. It protects the worksheet (Sheet1)and
allows users to use the AutoFilter dropdown lists.
