[jQuery] each help

[rayfidelity]

Hi,

I have this in each row (a couple of rows...)

<input type="text" class="num" name="qty[]" value=""
onkeyup="javascript:test();" />
<input type="text" class="num" name="price[]" value=""
onkeyup="javascript:test();" />
<input type="text" class="num" name="row_sum[]" value="" disabled />

i'd like to calculate the data

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

but the function doesn't function ;) Help anyone? someone?
