from the bottom of page 124 so that the first psshadowbox
points to all
of the psshadowbox elements of the psmatrix from the 
second psframebox and not just the first?

My problem more specifically is in the assigning of separate
to all of the elements of a psmatrix (in the book is printed
that all 
cells can be named), but this works only for the first two
elements of the psmatrix. If I insert for instance a
[name=C] before the third 
element of the matrix, then I get a latex error that some
number is missing 
at the end of the psframebox containing the matrix in

! Missing number, treated as zero.

Here is the whole code, if you uncomment the 14th and 16th
lines, the error
will appear:

    \end{psmatrix}} &
      [name=A]\Show{Goal} & [name=B]\Show{Criteria}\\
      \Show{Sub-goal} &
