Hi,

<html>
<head>
<s-cript type='text/j-avascript'>
function sumValues() {
var v1 = parseFloat(document.getElementById('box1').value);
var v2 = parseFloat(document.getElementById('box2').value);
document.getElementById('box3').value = v1 + v2;
}
</script>
</head>
<body>
<form on-change=sumValues()>
<input id='box1' type='text' />
<input id='box2' type='text' />
<input id='box3' type='text' />
</form>
</body>
</html>
