i improved it a bit, i made it an ini file, and also, used $style to put a check next to on or off

menu * {
  -
  Auto Login
  .$iif($group(#autologin).status == on,$style(1) ON,ON) {
    writeini login.ini Login Name $$?=\"User name on Undernet?\" 
    writeini login.ini Login Pass $$?=\"Pass used with Undernet?\" 
    echo 4,10***0 Undernet Login Enabled For $readini(login.ini,login,name)
    enable #autologin
  }
  .$$iif($group(#autologin).status == off,$style(1) OFF,OFF) {
    echo 4,10***0 Undernet Login Disabled For $readini(login.ini,login,name)
    disable #autologin
  }
