It doesn't have to be a form, but yes that would be the way to go. Presumably you'll be putting these calculated values somewhere on the page (not necessarily into a form field) - you can either have a "calculate" button that does the math, or automatically do the math whenever the inputs change values.

You can definitely attach events to it. But why are you creating the form with Javascript? Why can't you just write HTML for it? I'm sure it would be easier.

for some reason the span is removed form the code, probably due to the parser which converts code to XHTML
