I dont know whats wrong with this 

command /dupe:
  trigger:
    loop all items in the player's inventory:
    if 1st line of lore of the loop-item is "&cDupe Tool":
      if loop-item is held item:
      send "&cYou cannot dupe this item!"
      play sound "block.note_block.ping" at volume 2 and pitch 1 to the player
      stop
    give player held item
