Well the code you posted does that intentionally, it has the following lines

var aa=322.33, bb=298.22;
document.main.a.value=""+aa;  document.main.b.value=""+bb;

and that obviously has fixed values for aa and bb and assigns these 
values as the content of the form control each time the add function is 
called.

You probably want to give your function add two parameters e.g.
   function add (a, b) {
     ...
   }
and then in the form button you use
   <input type="button" value="add"
          onclick="add(this.form.elements.a.value, 
this.form.elements.b.value);">
