I have exactly this setup in a few sites - basically I have a form button that
submits the form back to the same template with the form fields filled with the
new calculated values. You can change the action of a form using javascript like
this: onClick="document.formname.action='thispage.cfm?action=calc';
document.formname.submit();"
You make the template check for the action=calc and then do the calculation and
populate the fields. Your other submit button is just a standard submit button.
