I am working on a "calculator" where you click on Form Input buttons and the numbers automatically Add together in the "Total" Input. However - I need to have Three (or more) Total Windows. And I would like to swap which "Total Window" you are using via a radio button.
I have it working with one "Total Window" - but I am unsure how to swap the Field that is being used in my calculations.
I started a jsfiddle: http://jsfiddle.net/bigfatdesigns/eSAPk/
