/* CalculateSum: this function has 3 arguments:
   Atext, Btext and form. It converts Atext and Btext to
   numbers using the built-in JavaScript "parseFloat" method.
   It then uses the form argument to output the sum of the
   numbers to the form\'s Answer field. Notice that the
   function does *not* need to know the the names of the
   form\'s input fields. Those values are passed as arguments.
   It does need to know that the form has a field named
   "Answer" so that it can put the result there. */
