Widget in footer doesn’t show result

Hi,
I installed the plugin and when in use in the homepage it works perfect. But I put it in the footer too as a widget. And when you hit the calculate button the result is now showing. I found out that if I scroll up the result is actually showing up on the page. But it makes no sence, because users would never think to hit the button and then scroll up. So how can I make it work on both places together?

Thanks!
Anna
