Calculation using Javascript

Question

var pricePerItemExVat = parseInt($("#ConsumerWSP").val()) / parseInt($("#ConsumerItemSellUnit").val());
var pricePerItemIncVat = pricePerItemExVat + (pricePerItemExVat * parseInt($("#pricingConsumerVat").text()));
var consumerPor = ((parseInt($("#itemRRP").val()) - pricePerItemIncVat) / parseInt($("#itemRRP").val())) * 100;
alert(consumerPor);

Even when all my fields have values(and also values greater than ZERO) the alert returns me a NaN.

Why Is it so ?

How may I do this calculation in javascript ?

Can you show us what each variable equals? – Lugia101101 Apr 21 '14 at 11:11 — Lugia101101, Apr 21 '14 at 11:11

You have get the text in-place of value. As per code you are trying to pricePerItemExVat divide by Empty. So pricePerItemIncVat value is "NaN".

$("#pricingConsumerVat").text()));

enter image description here

Let me know if any concern.

Edit 1:

var pricePerItemExVat = parseInt($("#ConsumerWSP").val()) / parseInt($("#ConsumerItemSellUnit").val());
alert(pricePerItemExVat );
var pricePerItemIncVat = pricePerItemExVat + (pricePerItemExVat * parseInt($("#pricingConsumerVat").val()));
alert(pricePerItemIncVat );
var consumerPor = ((parseInt($("#itemRRP").val()) - pricePerItemIncVat) / parseInt($("#itemRRP").val())) * 100;
alert(consumerPor);

Can you please put alert on every variable? For reference please check 'edit1' in above code snippet. Please provide value of each alert. – Jayesh Goyani Apr 21 '14 at 11:22
