Adding an amount to an integer......

[ballygowanboy]

i'll try and explain this as best i can.

i have a form with 3 radio buttons.

they have 3 values, 0, 5 and 10.

when the checkbox is checked, it adds that ammount to the total figure, currently 0.

i can't get it to work, maybe one of you guys could have a look at the code and tell where i'm going wrong, thanks.

<script language="javascript1.2">
 
function calculateTotal()
 
{
    var price,i;
 
for (i=0; i<document.formTotal.shipping.length;i++)
    {
        if (document.formTotal.shipping.checked=true)
        {
            parseInt (document.formTotal.total + 5);
        }
    }    
 
</script>
 
 

and the html.

<form name="formTotal" method="post" action="">
 
    <table width="100%" border="0" cellspacing="1" cellpadding="6">
      <tr>
        <td colspan="3" bgcolor="#FFF7D2"><span class="style3">Please choose your region for shipping </span></td>
        </tr>
      <tr>
        <td align="center"><span class="style1"><strong>Ireland<br />
        </strong>free </span><br />
          <input name="shipping" type="radio" /></td>
        <td align="center"><span class="style1"><strong>Other EU</strong><br />
          &euro;5<br />
</span>
          <input name="shipping" type="radio" value="5" /></td>
        <td align="center">&nbsp; <span class="style1"><strong>Rest of World</strong><br />
          &euro;10<br />
</span>
          <input name="shipping" type="radio" value="10" /></td>
      </tr>
    </table>
</form>
      <table width="100%" border="0" cellspacing="1" cellpadding="6">
        <tr>
          <td colspan="2" bgcolor="#FFF7D2"><span class="style3">Shopping Cart </span></td>
        </tr>
        <tr>
          <td><span class="style1">Quantity</span></td>
          <td><span class="style1" id="quantity">0</span></td>
        </tr>
        <tr>
          <td><span class="style1">Total</span></td>
          <td><span class="style1" id="total">0</span></td>
        </tr>
      </table>
