Trap command not working

Hi Folks -

For some reason, my trap command is not working. It's placed just prior to a normal exit:

Code:
#:: ------------------------------------------------------------------------

  echo "${_LCM_DIR} Life Cycle Management Backup Unsuccessful"                      
  echo ---------------------------------------------------------
  exit 1
  fi

However, in earlier threads this months, I was told to place the trap earlier in my script. When I do so, I get an error with this message :

Code:
trap: usage: trap [-lp] [arg signal_spec ...]

Thanks!
