sign gui

Dobri, mam problem z SIGN GUi, znalazlem pewna funkcje w internecie, ktora mi to umozliwia, lecz nie dziala pewna rzecz. System dziala na packetach. Gui od tabliczki normalnie sie wyswietla, lecz nie pisze tekst na tej otoz tabliczce.
Co moze byc problemem moi drodzy?

Kodzik:

 

function packetSignGUI(lines: strings, player: player):
    set {_loc} to location(0, 4, 0, {_player}'s world)
    set {_block} to type of block at {_loc}
    set block at {_loc} to sign
    loop {_lines::*}:
        (loop-index parsed as int) < 5
        set line (loop-index parsed as int) of block at {_loc} to "%colored loop-value%"
    wait a tick
    set {_packet} to new play_server_open_sign_editor packet
    set location pinfo 0 of {_packet} to {_loc}
    send {_player} packet {_packet}
    set block at {_loc} to {_block}
    
command /sign <player>:
    trigger:
        set {_lines::*} to "siema", "elo" and "Xd"
        send "%{_lines::*}%" to player
        packetSignGUI({_lines::*}, arg)
