Trap is designed to break the sequential flow of commands.
I can't see any reason to do that when the OP wants the
sequence:

    execute a script
    print a string

If you make your screen narrow before you cut and paste, you won't end
up with this mess, but something instead like:

       trap [-lp] [[arg] sigspec ...]
              The command arg is to  be  read  and
              executed  when  the  shell  receives
              signal(s) sigspec.  If arg is absent
              (and  there  is a single sigspec) or
              -, each specified signal is reset to
              its  original disposition (the value
              it had upon entrance to the  shell).
