Return selected radiobutton from group in Excel userform

I have an Excel userform that has a number of radio (option) buttons grouped together.

Is it possible to reference the GroupName of the radio buttons to identify which one has been selected?

I've tried me.myGroup, but Excel doesn't recognise it.

If possible, I would like to write something like;

myVar = me.mygroup

Is this possible in Excel 2013?

If you have set the GroupName property on the option buttons like this:

Then you can refer to that property in a loop of the controls where you are looking to see that the control's TypeName is OptionButton and that the GroupName is a match:

Option Explicit

Private Sub CommandButton2_Click()
    Dim opt As MSforms.OptionButton

    Set opt = GetSelectedOptionByGroupName("MyGroup")

    If Not opt Is Nothing Then
        MsgBox opt.Name
    Else
        MsgBox "No option selected"
    End If

End Sub

Function GetSelectedOptionByGroupName(strGroupName As String) As MSforms.OptionButton

    Dim ctrl As Control
    Dim opt As MSforms.OptionButton

    'initialise
    Set ctrl = Nothing
    Set GetSelectedOptionByGroupName = Nothing

    'loop controls looking for option button that is
    'both true and part of input GroupName
    For Each ctrl In Me.Controls
        If TypeName(ctrl) = "OptionButton" Then
            If ctrl.GroupName = strGroupName Then 
                Set opt = ctrl
                If opt.Value Then
                    Set GetSelectedOptionByGroupName = opt
                    Exit For
                End If
            End If
        End If
    Next ctrl

End Function
