help with conditionals in recipe

I have a short recipe below that seems to work except for that the last line
in curly braces is not executing causing the perl subroutine rip_attachment
to not get called.
I was wondering if someone might me able to tell me what I am doing wrong?

Thanks,

Richard

:0 W # send to test_subject.pl to check for PO no.
* ? /usr/bin/perl -e 'require "/home/richard/.pmdir/test_subject.pl";
test_subject($ENV{SUBJECT});'
    # failed subject test
|( formail -rI"From: Replys automatically discarded <[email protected]>";
\
   echo "Your mail has been returned."; \
   echo "It was NOT received because it does not contain a valid PO in the
subject"; \
   echo "Please resubmit with a valid PO number in the subject line."; \
 ) | /usr/sbin/ssmtp -oi -t

:0:  #2nd colon means use locking so we don't get 2 files at once in friends
{ # passed subject tes. It has a valid PO no
  :0 c     # copy to freinds and invoices
  friends

  :0
  invoices

  :0 W #rip the attachments
  * ? /usr/bin/perl -e 'require "/home/richard/.pmdir/test_subject.pl";
rip_attachments($ENV{SUBJECT});'

}
