Please review my web application design

Hi Antony,

In my opinion, you have to work on UI/UX part.
When I enter the amount and click on Add/Remove VAT button, then the new popup comes and it shows the calculated result.
I think it's not a proper way to show results. You can show results just below the calculator and remaining fields stays as it is.
Look at this one: vat-calc_dot_net
