<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

</head>

<script language="javascript">

if (document.orcamento.menu1.value == "") {

  if (document.orcamento.select.value == "") {

  if (document.orcamento.select2.value == "") {

    if (document.orcamento.select3.value == "") {

    alert("selecione pelo menos 1 combo");

    return false;

    }
