Mutually Exclusive Selection - without radio buttons

Attached file has a sample to describe what I am trying to accomplish.  My goal is to be able to select an option within the group and once the selection is made the rest of the options should become unavailable for selection, basically the same concept with radio buttons.  I could have achieved this using radio buttons in fact this is how it is done currently for the users, but the new requirement is forcing us to eliminate all the control objects from the file, that is all active x controls and form control objects like checkboxes, option buttons, drop downs etc.  In this case I need a logic, code or a setup to simulate what can be accomplished via radio buttons.  On the file there is also a problem description in a box.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Here's a workbook where Format Cells->Protection and then unchecked "Locked" for the two ranges. I then password protected the sheet (password = "Password") and added this code.
Private Sub Worksheet_Change(ByVal Target As Range)
ActiveSheet.Unprotect Password:="Password"
If Not Intersect(Target, Range("H2:H5")) Is Nothing Then
    Range("H2:H5").Locked = True
End If
If Not Intersect(Target, Range("O2:O5")) Is Nothing Then
    Range("O2:O5").Locked = True
End If
ActiveSheet.Protect Password:="Password"

Open in new window

After doing that I selected "Yes" in H4 which caused the code to lock range(H2:H5). You can try it with the other range.

This does it without any sheet protecting.

Option Explicit
Private mbSelectedH As Boolean
Private mbSelectedO As Boolean

Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range("H2:H5")) Is Nothing Then
    mbSelectedH = True
End If
If Not Intersect(Target, Range("O2:O5")) Is Nothing Then
    mbSelectedO = True
End If

End Sub

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Not Intersect(Target, Range("H2:H5")) Is Nothing Then
    If mbSelectedH Then
        Beep
        Range("H6").Select
    End If
End If
If Not Intersect(Target, Range("O2:O5")) Is Nothing Then
    If mbSelectedO Then
        Beep
        Range("O6").Select
    End If
End If
End Sub

Thank you!

You're welcome and I'm glad I was able to help. I've attached another way that I rather like. (I only did it for the first set of options). The code in Workbook_Open is not really necessary after the buttons are formatted once.

In my profile you'll find links to some articles I've written that may interest you.
