here i am trying to do calculation for javascript dynamic rows. i have done auto multiplication in few rows using this function . but i want to calculate the tax percentage. how can i do that? help..

<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script>
var $k = jQuery.noConflict();

$k.fn.sum = function() {
    var sum = 0;
    $k(this).each(function() {
        sum += parseFloat($k(this).val());
    });

    return sum;
}

$k(function() {
    $k('select[name^=noofnights], input[name^=unitprice]').live("keyup", function() {
        var noofnights = parseFloat($k(this).parent().find('select[name^=noofnights]').val());
        var unitprice = parseFloat($k(this).parent().find('input[name^=unitprice]').val());
        $k(this).siblings('input[name^=linetotal]').val(noofnights * unitprice);

        var sum = $k('input[name^=linetotal]').sum();

        $k('#subtotal').val(sum);
        $k('#tax').val(Math.round(sum * 10 * 100) / 100);
        $k('#total').val(Math.round((sum + Math.round(sum * 10 * 100) / 100) * 100) / 100);
    });

    $k('.add').live('click', function() {
        $k(this).closest('.item').after($k('#template').html());
        $k('form .item').each( function(i) {
           $k(this).find('input[name^=num]').val(i+1);
        });
    });
});
</script>

    });

    return sum;
}

$k(function() {
    $k('input[name^=rate], input[name^=tax]').live("keyup", function() {
        var rate = parseFloat($k(this).parent().find('input[name^=rate]').val());
        var tax = parseFloat($k(this).parent().find('input[name^=tax]').val());
        $k(this).siblings('input[name^=nettotal]').val(rate/100 * tax);

        var sum = $k('input[name^=nettotal]').sum();

        $k('#finalnettotal').val(sum);
     });

    $k('.add').live('click', function() {
        $k(this).closest('.item').after($k('#template').html());
        $k('form .item').each( function(i) {
           $k(this).find('input[name^=num]').val(i+1);
        });

i tried and finally i did it... if anyone wants javascript dynamic row with calculation na use this code.. it works perfectly...:-)

var $k = jQuery.noConflict();

$k.fn.sum = function() {
    var sum = 0;
    $k(this).each(function() {
        sum += parseFloat($k(this).val());
    });

    return sum;
}

$k.fn.calc = function() {
    var calc = 0;
    $k(this).each(function() {
        calc += parseFloat($k(this).val());
    });

    return calc;
}

$k.fn.final = function() {
    var final = 0;
    $k(this).each(function() {
        final += parseFloat($k(this).val());
    });

    return final;
}

$k(function() {
    $k('select[name^=noofnights], input[name^=unitprice], input[name^=tax]').live("keyup", function() {
        var noofnights = parseFloat($k(this).parent().find('select[name^=noofnights]').val());
        var unitprice = parseFloat($k(this).parent().find('input[name^=unitprice]').val());
        var tax = parseFloat($k(this).parent().find('input[name^=tax]').val());
        $k(this).siblings('input[name^=linetotal]').val(noofnights * unitprice);
        var linetotal = parseFloat($k(this).parent().find('input[name^=linetotal]').val());
        $k(this).siblings('input[name^=nettotal]').val(linetotal/100 * tax);
        var nettotal = parseFloat($k(this).parent().find('input[name^=nettotal]').val());

        var sum = $k('input[name^=linetotal]').sum();
        var calc = $k('input[name^=nettotal]').calc();
        var final = $k('input[name^=linetotal], input[name^=nettotal]').final();

         $k('.subtotal').val(sum);
         $k('#finalsubtotal').val(calc);
         $k('#finaltotal').val(final);
     });

    $k('.add').live('click', function() {
        $k(this).closest('.item').after($k('#template').html());
        $k('form .item').each( function(i) {
           $k(this).find('input[name^=num]').val(i+1);
        });
    });
});
