Creating 2 pairs of independent Radio btns

[Oldschool]

I can only have 1 checked at one time...

How to I make them independent?

#include <GUIConstants.au3>
GUICreate("My GUI radio") ; will create a dialog box that when displayed is centered
GUICtrlCreateLabel("CRM:", 40, 10)
$radio1 = GUICtrlCreateRadio ("Enabled", 20, 30, 60, 20)
$radio2 = GUICtrlCreateRadio ("Disabled", 90, 30, 60, 20)
GUICtrlSetState ($radio2, $GUI_CHECKED)
GUICtrlCreateLabel("Notice To e-mail:", 240, 10)
$radio3 = GUICtrlCreateRadio ("Enabled", 220, 30, 60, 20)
$radio4 = GUICtrlCreateRadio ("Disabled", 290, 30, 60, 20)
GUICtrlSetState ($radio4, $GUI_CHECKED)

GUISetState ()      ; will display an  dialog box with 1 checkbox

; Run the GUI until the dialog is closed
While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            ExitLoop
        Case $msg = $radio1 And BitAND(GUICtrlRead($radio1), $GUI_CHECKED) = $GUI_CHECKED
            MsgBox(64, 'Info:', 'You clicked the Radio 1 and it is Checked.')
        Case $msg = $radio2 And BitAND(GUICtrlRead($radio2), $GUI_CHECKED) = $GUI_CHECKED
            MsgBox(64, 'Info:', 'You clicked on Radio 2 and it is Checked.')
        Case $msg = $radio3 And BitAND(GUICtrlRead($radio3), $GUI_CHECKED) = $GUI_CHECKED
            MsgBox(64, 'Info:', 'You clicked the Radio 1 and it is Checked.')
        Case $msg = $radio4 And BitAND(GUICtrlRead($radio4), $GUI_CHECKED) = $GUI_CHECKED
            MsgBox(64, 'Info:', 'You clicked on Radio 2 and it is Checked.')
    EndSelect
