JavaScript could work, with the potential problem that JS-disadvantaged folk
won't see anything. I think if it were me, I'd try putting the whole FM call
and data processing loop in a function, which also returns a variable
containing the final figures you need. That way you can take the function's
output (containing the FM data and your custom variable/s) and process and
display them as required. Of course, I say all this off the top of my head
and without any insight into how your code currently works.
