Need a fresh pair of eyes on some JavaScript code

The JavaScript code in the attached story file works perfectly when the project runs in Flash but not in html5.  When you tab to the next field in the html version the totals increment by some crazy values. 

I have attached a flash version and an html5 version so that you can see the difference.

Falsh output: https://360.articulate.com/review/content/25ab0d95-fdc4-4511-85aa-e87540278bb0/review

I have been looking at the code for so long now that I think I need some fresh eyes on it.  I have attached the story 2 file if anyone wants to take a look and help me out.
