Adding the values of Radio buttons

I believe you actually need checkboxes instead of radio buttons. This bit of example code is in javascript as it is more widely accepted by browsers...
There are other ways of doing this, but this one is probably the easiest to understand.

Code:
<html>
<head>
<script language="javascript">
function Calculate(){
var Total = 0;
var maxRadio = 3;
for (var i=1;i<=maxRadio;i++){
if (eval("document.forms.frmDemo.chk" + i + ".checked")==true){
Total += parseFloat(eval("document.forms.frmDemo.chk" + i + ".value"))
}
}
alert("Your total is: $" + Total)
}
</script>
</head>
<body>
<form id=frmDemo>
<input type=checkbox value="30.00" id=chk1>Shirt: $30.00<br>
<input type=checkbox value="47.50" id=chk2>Pants: $47.50<br>
<input type=checkbox value="65.37" id=chk3>Silk Tie: $65.37<br><br>
<input type=button value="Calculate" onClick="Calculate()">
</form>
</body>

As requested. The javascript is left in so you can compare the two languages...
