If you already have the outlining applied, you can protect the worksheet in code
(auto_open/workbook_open??).

Option Explicit
Sub auto_open()
With Worksheets("sheet1")
.Protect Password:="hi", userinterfaceonly:=True
.EnableOutlining = True
End With
End Sub

It needs to be reset each time you open the workbook. (excel doesn't remember
it after closing the workbook.)

If you're new to macros, you may want to read David McRitchie's intro at:

You didn't do anything wrong--that's the way excel works.

Hi,

I am new to outlining data. I created an outline and I want to hide the
formulas through worksheet protection. However, I get an error message when
I try to use the outline. Is there something that I am not doing right?

Thanks
