I used to use \FPadd a fair bit, and I don't see anything wrong with
your syntax. I used to skip the first pair of curly braces (i.e.,
\FPadd\a{2}{3}), but that's the only difference I can see. Also, be sure
you're including the proper parts of the fp package -- it consists of a
number of files. IIRC, \usepackage{fp} includes them all.

Without a minimal example that demonstrates the problem, that's about
all I can say. Send me one off-list if you like (since it is somewhat OT
here).
