All,



I can't see why the code below is producing this error:



! Missing number, treated as zero.

<to be read again>

                    !

l.15   \psxTick[linecolor=red](1.5){x_0}


?



\documentclass[12pt]{article}



\usepackage{pst-pdf}

\usepackage{pst-bar}

\usepackage{pstricks-add}

\usepackage{pst-plot}

\usepackage{pst-tree}



\begin{document}



\begin{center}

           \psset{unit=0.125in}

           \begin{pspicture}(-8,-2)(8,0.5)

           \psaxes[arrowscale=1.5,arrows=<->,yAxis=false,labels=none] 
(0,0)(-8,0)(8,0)

           \psxTick[linecolor=red](1.5){x_0}

           \uput[270](0,0){$0$}

           \uput[270](7,0){$7$}

           \psdots*[linecolor=red,dotsize=3pt 3](#sa,0)(#sb,0)(#sc,0) 
(#sd,0)

           \end{pspicture}

\end{center}



\end{document}
