2 i dont understand what u mean ?

ON *:TEXT:-addnote *:#: {
;//  when you type the command ''-addnote word word etc etc'', is adding a line in the file even if the same row already exists.
;// example: frederik type: -addnote MoMy not understand anything about English
;// in the file addnote.txt will add the line '' Added by frederik - Notes MoMy not understand anything about English'' date -
;// If you throw the same command with the same sentence, get the message ''Sorry this [FB ID]: ( -addnote ) is already in DT DateBase for [Note]'' etc etc 
;// because there is a variable %note-addnote(etc-etc) but the file will add a new row duplicates.

  write addnote.txt Added by $nick - Notes $3 - Facebook ID $2 - $asctime -
  fbnumber $2
  if (!$($+(%,note,$2),2)) {
    set $+(%,note,$2) ( $3- ) $asctime 
    msg $chan 1[04Note]: $3- ,has been added to Dt Database . by $nick for 1[04FB ID]: ( $2 ) Date : $asctime | load -rs addnote.txt
  } 
  else {
    msg $chan $nick Sorry this 1[04FB ID]: ( $2 ) is already in DT DateBase for 1[04Note]: ( $3- ). 
  } 
}

and this thing happens on all the events on text that you wrote
