Graphics, Figures & Tables ⇒ Incomprehensible Error in Code for Tree

[mjperrone]

I can't seem to figure out what's wrong with this.

Code: Select all

\documentclass[12pt]{report}
\usepackage{tikz-qtree}

\begin{document}
  \begin{tikzpicture}[level distance=70pt,sibling distance=50pt]
    \Tree [.$(x<0)$
      \edge node[auto=right]{1}; 
      [.(a) 
        \edge node[auto=right]{1}; 
        [.$f_1();$ ] 
        \edge node[auto=left]{0};
        [.(b) 
          \edge node[auto=right]{0};
          [.$f_1();$ ] 
          \edge node[auto=left]{1}
	  [.$f_2();$ ] ] ]
	\edge node[auto=left]{0}; 
	[.(b)
        \edge node[auto=right]{0};
          [.$f_1();$ ] 
          \edge node[auto=left]{1};
          [.$f_2();$ ] ] ] ]
  \end{tikzpicture}
\end{document}

I get this error.

Hi, a semicolon is missing at the end of line 15.
