[pstricks] A little bit more complicated function definition fails again. Was: Can't use a mathematical function defined with FPeval in \psplot

\documentclass{article}
\usepackage[nomessages]{fp}
\usepackage{pst-plot}
\def\Vre{350}

\begin{document}

\edef\nonr#1#2{2*((#2)/2)^(1/3)/((2)^0.5*(#1))+(6)^0.5/2-1}
\edef\myMathFunction#1#2{(\nonr{#1}{#2}) * 5 - (\nonr{#1}{#2})^2}

\FPeval\myMathFuncTwo{\myMathFunction{2}{(\Vre)}}

\pspicture[shift=*](-1,0)(15,7)
\psaxes{->}(14.5,7.5)
\psline[linecolor=red](0,0.5)(2,0.5)
\psline[linecolor=red](2,0.5)(2,\myMathFuncTwo)
\psplot[algebraic,linecolor=red,linewidth=1.5pt]{2}{5}{%
  \myMathFunction{x}{\Vre}%
}
\psplot[algebraic,linecolor=red,linewidth=1.5pt]{5}{14}{%
  \myMathFunction{x}{\Vre}%
}
\endpspicture
