I think you are right ... I forgot I have another macro that I created ... I
get the error Run-time error '1004', Application-defined or object-defined
error and when I click on the debugger it goes to the macro below. It is a
simple recorded macro so I am not sure why I get this error.


Sub Macro1()
Range("D3").Select
ActiveCell.FormulaR1C1 = "=SUM(R[3]C[1]:R[3]C[10])"
Range("D4").Select
End Sub

I do not get any errors when I run the code, so I'm not sure what to tell
you about that... the posted code runs fine for me.. not errors. I did
notice that I forgot to place a limit on the entry in D3 that the code
reacts to (unlike the Select Case block, the calculation replacing the it
will happily calculate a value for any number entered in D3); the code below
places the appropriate range trapping in the code.

Private Sub Worksheet_Change(ByVal Target As Range)
Dim wSheet As Worksheet
If Target.Cells.Count = 1 And Target.Address = "$D$3" Then
If Range("D3").Value = 1 And Range("D3").Value <= 10 Then
Me.Unprotect Password:="Secret"
Me.Columns("E:N").Hidden = False
Me.Columns(Chr(79 - Target.Value) & ":N").Hidden = True
Me.Protect Password:="Secret", UserInterFaceOnly:=True
End If
End If
End Sub

With respect to the Protect/Unprotect issue I raised... I was referring to
this part from your original code...

For Each wSheet In Worksheets
wSheet.Protect Password:="Secret", UserInterFaceOnly:=True
Next wSheet

This code snippet runs through *each* sheet in the workbook and turns on the
protection. My point was that you did not have to iterate through *every*
sheet in the workbook because the running code only unprotected the active
sheet... the other sheets remained protected, so there is no need to loop
through them turning on the protection that is already on.

I tried this & now I get a different error ... Run-time error '1004',
Application-defined or object-defined error.

The reason I had to add that specific password protection is so columns
will
be hidden based the choice in the drop down box.

The only thing that should be unprotected are specific columns depending
on
a user's choice with a drop down box. There is a limited number of cells
that a user can input into.

You missed the equal sign in your Target.Address test. Also, since only
the
active sheet is being unprotected at the beginning of the routine, then I
would think that should be the only one being re-protected again inside
this
routine. In addition to that, I noticed a mathematical relationship in
the
Columns ranges versus the content of D3 that allows the entire Select
Case
block to be replaced with a single line of code. Here is the routine
after
the above are incorporated into it...

Private Sub Worksheet_Change(ByVal Target As Range)
Dim wSheet As Worksheet
If Target.Cells.Count = 1 And Target.Address = "$D$3" Then
Me.Unprotect Password:="Secret"
Me.Columns("E:N").Hidden = False
Me.Columns(Chr(79 - Target.Value) & ":N").Hidden = True
Me.Protect Password:="Secret", UserInterFaceOnly:=True
End If
End Sub

This should do what the OP's original code was trying to do.

You have a couple of potential problems...
This line
If Target = Range("D3") Then
is the same as
If Target.Value = Range("D3").Value Then
You probably wanted
If Target.address "$D$3" Then

Your lastcase is the only one that does a protection and even though
you
have userinterface set to true there will still be some things that
macros
will not be able to do.

There is nothing in there that will necessarily generate a type
mismatch...
