Hello!
Pls help!

I need to provide a veticle line before and after the equation.
The command I have used below, which produced just a left curly 
bracket. Also, I need some space to provide between the each segment. 
eg.  1 \cdot 2 (space) 2 \cdot 1 (space) 1.  What command should I use to 
produce 
these.         

\begin{eqnarray}
S^2 = - \det \cases{1 \cdot 1  2 \cdot 1 3 \cdot 1 \cr
                    1 \cdot 2  2 \cdot 2 3 \cdot 2 \cr
                    1 \cdot 3  2 \cdot 3 3 \cdot 3}
\end{eqnarray}

Thanks,
Manju
