单选按钮复制到文本字段的值

我终于学会了如何应用j-query来计算联系人表单7的单选按钮格式。我遇到的问题是，我必须将格式（小会话100.00美元）反转为（100.00小会话）才能进行计算。我很想拥有它（迷你会话100.00美元）。我也很想复制已选择复制到文本字段的单选按钮的值。

这是我的表格，它是在联系表格7表格中建立的。

    <p>Your Name (required)<br />

Total Amount: <span id="total"></span>
Deposit Amount: <span id="deposit"></span>
Balance Amount: <span id="balance"></span> 
Balance Due By: [text RYSBA2 20/20 id:RYSBA2]
<p>How would you like to pay the remaining balance (due prior to the session) via:<br />
[radio RYSPB id:RYSPB class:radio-vertical "A PayPal Invoice Apx. 2 weeks before the session." "A PayPal Invoice Apx. day before the session." "I will pay the balance the day of the session With a debit or credit card."]
<p>[submit "Send"]</p>

我的java脚本来计算和复制字段

<script type="text/javascript">
    $(document).ready(function() {
        $("#RYSSD1").keyup(function() {
            $('#RYSBDB').val($(this).val());
            $('#RYSBA2').val($(this).val());
       });
        var inputs = $('input[name="RYSSPT"], input[name="RYSEP"]');
        $(inputs).click(function() {
            var total = 0;
            $(inputs).filter(':checked').each(function() {
                total = total + parseInt($(this).val());
            })
            $('#total').html('$' + total);
            $('#deposit').html('$' + (total / 2));
            $('#balance').html('$' + (total / 2));
});
    });
</script>

我的下一个问题是如何将单选按钮值复制到文本字段以及如何将其添加到脚本中。我还有一个问题，当我得到总数时，最后的0没有显示。

仍在处理表单

这能让单选按钮值复制到命名的文本字段吗

  $('#1').blur(function() {
  $('#3').val($(this).val());
});

如何获取命名文本字段的单选按钮值。
