wykrywanie tabliczek

On rightclick on sign:
    if line 1 is "&6&lCOLOR&c&lMATCH":
        if line 4 is "&akoloroweNiebo":
            execute player command "/cm join"
            if {cmgame::liczba} > 0:
                set line 3 to "&eOczekiwanie"
            if {cmgame::liczba} = 0:
                set line 3 to "&6Aktywna"
            set line 2 to "&a%{cmgame::liczba}%&f/&a20"
command /tabliczka:
    trigger:
        give sign named "&a&lkoloroweniebo" to player

on place of sign:
    name of event-block is "&a&lkoloroweniebo":
        add location of event-block to {tabliczka.*}

every 1 seconds:
    loop {tabliczka.*}:
        set {_l} to loop-value
        set line 2 of block at {_l} to "&a%{cmgame::liczba}%&f/&a20"

nie działa mi every 1 seconds: bo mi nie wykrywa tabliczki
