Problem z otwieraniem gui

Mam problem z skryptem. Otóż gdy nie działa w nim otwieranie gui. Oto jego fragment:

I gdy skrypt dochodzi do "[execute player command "/pogoda pora"] nic sie nie dzieje.

command /pogoda [<text>]:
    trigger:
        if arg 1 is not set:
            open chest with 1 rows named "&2&lUstawienia" to player
            wait 2 ticks
            format slot 0 of player with 1 of 160:15 named " " to be unstealable
            format slot 1 of player with 1 of 160:15 named " " to be unstealable
            format slot 2 of player with 1 of 160:15 named " " to be unstealable
            format slot 4 of player with 1 of 160:15 named " " to be unstealable

            format slot 3 of player with 1 of 347 named "&3Ustawienia Pory Dnia" to close then run [execute player command "/pogoda pora"]
            format slot 5 of player with 1 of 370 named "&3Ustawienia Pogody" to close then run [execute player command "/pogodynka"]
        if arg 1 is "pora":
            open chest with 1 rows named "&3&lUstawienia Pory Dnia" to player
            wait 2 ticks
            format slot 0 of player with 1 of 160:15 named " " to be unstealable
