Total field always visible even when user scrolls

In other words, how do I get the total at the bottom of the page to appear with the screen as it scrolls. That way the customer can make changes while seeing his/her total. Something on the side of the form would work too.

From what I understood you wish the total to be permanently visible while user is scrolling the page. 

For this you need to add a css code similar to this one:

#id_13

{position: fixed;

background-color: #ffffff;

z-index: 10;}

You can test the demo form:
