[MX] : form (POST) x ASP

[eng]

dovrei implementare questo form:

<form name="frmMailingList" method="post" action="mailing_list.asp" target="mailingList" onSubmit="window.open('', 'mailingList', 'toolbar=0,location=0,status=0,menubar=0,scrollbars=0,resizable=1,width=400,height=200')">
  <table width="143" border="0" cellspacing="2" cellpadding="0" align="center">
    <tr> 
      <td class="text">Il tuo indirizzo email:</td>
    </tr>
    <tr> 
      <td> 
        <input type="text" name="email" maxlength="35">
      </td>
    </tr>
    <tr> 
      <td align="left" class="text"> 
        <input type="radio" name="mode" value="add" id="add" checked><label for="add">Iscrivimi</label>

        <input type="radio" name="mode" value="delete" id="delete"><label for="delete">Cancellami</label></td>
    </tr>
    <tr>
      <td align="center">
        <input type="submit" name="Submit" value="Invia">
      </td>
    </tr>
  </table>
</form>
<center>

Ho messo il campo input email, i due radio button , ma non so come implementare:
1-
name="mode" value="add"
name="mode" value="delete"
2-il codice da associare al button Subsmit e'

oon(release){
getURL("http://www.miosito.org/mailing_list.asp, POST");
}

??

ma posta le variabili email e mode?

specifico che il form non deve ricevere indietro nessuna variabile da mailing_list.asp
