One way to do it would be to remove the submit button, and replace it with a standard button which instead of submitting the form calls a function when clicked, the function can then calculate the total, enter the results into the total fields, and then submit the form.

 

 

 

Or you could have a function that is called every time the user changes any selections which updates the totals live.

 

 

 

I don't have time to write anything right now as I'm off to bed, so if nobody else has done it by tomorrow I will probably take a look.
