What kind of error messages do you get? Using $2 $3 $4 ... in message
boxes works fine, but you need to send a list into this message box.
You can create such a list with [pack 0 0 0 0 ...].

So for example this should work:

  [nbx] [nbx] [nbx] [nbx]
  |     |     |    /
  [pack 0  0  0  0]
  |
  [whatever $1 $2 $3 and $4(
  |
  ...

See section 2.6.5 "dollar signs" of the Pd manual for the gory
details: http://crca.ucsd.edu/~msp/Pd_documentation/x2.htm#s6.5 and
the help patch: doc/2.control.examples/14.dollarsigns.pd
