ciao,ho un problema di passaggio valori dal form a una funzione js che dovrebbe stampare i valori in una textarea senza sovrascrivere. grazie anticipatamente,vi posto il codice :

(in particolare la funz add dovrebbe accettare il valore di ogni singolo select e scriverlo sulla textarea)



<script type="text/javascript">


function add(var value){


document.ordine.GetElementById('text').value=value ;

}



function controlla(){
if(document.ordine.codCliente.value==""){
alert("Inserire codice Cliente");
return(false);}
}
</script>
</head>


<body>

<h4>GESTIONE ORDINI</h4>




<form name="ordine" action="mailordine.php" method="post" onsubmit="return controlla()">








<table style="text-align: left; width: 549px; height: 140px;" border="1" cellpadding="2" cellspacing="2">
