Dlaczego nie działa zmienna tymczasowa - wyświetla "<none>"

Bo zmienna tymczasowa działa tylko w jednym evencie

@jaku49, poprawisz mi ten skrypt?

command /testgui [<player>] [<text>]:
    trigger:
        open chest with 1 row named "TESTOWEGUI" to player
        set player's current inventory's slot 1 to stone named "TEST"
        set {gracz9999::%player%} to player
        set {argument9999::%player%} to arg 1
        stop
       
on inventory click:
    if inventory name of player's current inventory is "TESTOWEEGUI":
        if clicked slot is 1:
            cancel event
            send "&7>> &cGRACZ: %{gracz9999::%player%}%" to player
            send "&7>> &aARGUMENT: %{argument9999::%player%}% to player
