[OS X TeX] Calculate with LaTeX and fp.sty

[Friedrich Vosberg]

Morning.

I've spent the whole weekend but did not find a solution.

Does somebody of you have an idea, how to calculate the following  
example including the hidden part in which the result of the previous  
calculation should be processed?

\documentclass{minimal}
\usepackage{fp}
\usepackage{numprint}
%
\newcommand{\rtink}[1]{%
     \def\Inkasso{#1}
     \def\RVGInkasso{%
         \FPiflt{#1}{2500.01}
             \FPset{\sum}{#1}%
             \FPmul{\sum}{\sum}{.01}%
             \FPround{\sum}{\sum}{2}%
             \numprint{\sum}%
         \else%
         \FPiflt{#1}{10000.01}
             \FPset{\sum}{#1}%
             \FPsub{\sum}{\sum}{2500.00}%
             \FPmul{\sum}{\sum}{.005}%
