Hi,

I have a list of names and columns of data, i am going to name all these ranges

I would like some code that if you click anywhere in that named range you get prompted to enter a password that i can nominate

Has anyone got such code?

Thanks
Seamus

This this code.  Paste it into the worksheet code pane for the worksheet containing the cells you want to protect.  Modify the code to match the range names in your worksheet.  I used names rngTemp1, rngTemp2, rngTemp3.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim PWord As String
PWord = "MyPassword"
If Not Application.Intersect(Range("rngTemp1"), Target) Is Nothing Then
    If Not PWordIsCorrect(PWord) Then Range("A1").Select
ElseIf Not Application.Intersect(Range("rngTemp2"), Target) Is Nothing Then
    If Not PWordIsCorrect(PWord) Then Range("A1").Select
ElseIf Not Application.Intersect(Range("rngTemp3"), Target) Is Nothing Then
    If Not PWordIsCorrect(PWord) Then Range("A1").Select
End If
End Sub

Function PWordIsCorrect(sPass As String) As Boolean
Dim s As String
s = InputBox("Enter the password", "Password required")
If s = sPass Then PWordIsCorrect = True Else PWordIsCorrect = False
End Function

Small hint for using Kyle's solution:

You'll ideally want to protect the VBProject and the workbook itself with a password too, otherwise nothing's stopping the users from hitting ALT+F11 and looking at the code to find the right password.

Here's an updated version.  I made the assumption that as soon as someone entered the correct password they should be allowed to keep working in the range until they clicked outside the boundaries.  At that point they will need to enter the password again to re-enter the range.  You will need to specify a cell into which the code can dump a variable.  In the example I used "I2".  Modify as necessary.
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim PWord As String
PWord = "MyPassword"
If Not Application.Intersect(Range("rngTemp1"), Target) Is Nothing Then
    If Range("I2") <> "r1" Then
        If Not PWordIsCorrect(PWord) Then Range("A1").Select Else Range("I2") = "r1"
    End If
ElseIf Not Application.Intersect(Range("rngTemp2"), Target) Is Nothing Then
    If Range("I2") <> "r2" Then
        If Not PWordIsCorrect(PWord) Then Range("A1").Select Else Range("I2") = "r2"
    End If
ElseIf Not Application.Intersect(Range("rngTemp3"), Target) Is Nothing Then
    If Range("I2") <> "r3" Then
        If Not PWordIsCorrect(PWord) Then Range("A1").Select Else Range("I2") = "r3"
    End If
Else
    Range("I2") = "Nothing"
End If
End Sub

Function PWordIsCorrect(sPass As String) As Boolean
Dim s As String
s = InputBox("Enter the password", "Password required")
If s = sPass Then PWordIsCorrect = True Else PWordIsCorrect = False
End Function

That looks really good Kyle, but i need each range to have a different password, not one password for the whole lot

Thanks

Here you go.  Now you need to specify a unique password for each range.  Modify as necessary.
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim sPW1 As String, sPW2 As String, sPW3 As String
sPW1 = "PW1"
sPW2 = "PW2"
sPW3 = "PW3"
If Not Application.Intersect(Range("rngTemp1"), Target) Is Nothing Then
    If Range("I2") <> "r1" Then
        If Not PWordIsCorrect(sPW1) Then Range("A1").Select Else Range("I2") = "r1"
    End If
ElseIf Not Application.Intersect(Range("rngTemp2"), Target) Is Nothing Then
    If Range("I2") <> "r2" Then
        If Not PWordIsCorrect(sPW2) Then Range("A1").Select Else Range("I2") = "r2"
    End If
ElseIf Not Application.Intersect(Range("rngTemp3"), Target) Is Nothing Then
    If Range("I2") <> "r3" Then
        If Not PWordIsCorrect(sPW3) Then Range("A1").Select Else Range("I2") = "r3"
    End If
Else
    Range("I2") = "Nothing"
End If
End Sub

Function PWordIsCorrect(sPass As String) As Boolean
Dim s As String
s = InputBox("Enter the password", "Password required")
If s = sPass Then PWordIsCorrect = True Else PWordIsCorrect = False
End Function
