Trying to create a running total with radio buttons

[alexphd]

Hey All,

So, I have a product that cost 1050.00 dollars by itself. With radio buttons I want the user to be able to add extra features to it or take away certain features from it. Which would increase or decrease the total price. While they are doing that I want the total price showing. Here is what it looks like so far so you could get a better idea.

Why not do something like that, and it works in firefox :)

<script type="text/javascript">
document.forms['order'].onclick = DoMath;
var total;
function DoMath(){
total = 0;
for(i = 0; i < document.forms[0].length; i++)
if(document.forms[0][i].type == 'radio')
if(document.forms[0][i].checked){
total += parseInt(document.forms[0][i].value);
}
document.forms[0]['total'].value = "$" + total;
}

</script>
