[jQuery] row clone and calculation

[rayfidelity]

Hi,

I have a table with input fields (array of them)...i can add new rows
through clone...the problem is that i would like to calculate the
numbers in the fields and display the sum at the end (both row sum and
final sum) and i don't know how.

Here's what i got:

function calc(){
        var price = $("[EMAIL PROTECTED]'price[]']").val();
        var qty = $("[EMAIL PROTECTED]'qty[]']").val();
        res = price * qty;
        $("[EMAIL PROTECTED]'row_sum[]']").val(res);

        var sum = $("input:disabled").sum();
        $(".sum").text(sum);
}

The function is called on input keyup. Row sum is shown in the
disabled input...

Obviously this doesn't work when i add a row...it only works for the
first row which is hardcoded...

Thanks in advance!
