Jak zapisać lokalizacje bloku postawionego do zmiennej i jak później się do tego odwołać?

Witam, mam problem, poniewaz po postawieniu cuboidy z nazwa "&6Zabezpieczenie działki" wszystko działa dobrze, tworzy sie cuboida poza tym, ze gdy postawie zwykly jukebox gdzie kolwiek i go zniszcze, zniszczy się tez cuboida, chcialem pobawic sie z tym zeby zapisywalo lokalizacje po postawieniu bloku i zeby dalo sie zniszczyc tylko ten okreslony blok po lokalizacji w tym przypadku jukebox z nazwa "&6Zabezpieczenie działki", ale nie wiem co zrobic i jak to dziala. Z gory dzieki

variables:
    {cuboida.%player%} = false
 
options:
    teren: 30
 
on place jukebox:
    if name of player's tool is "&6Zabezpieczenie działki":
        if {cuboida.%player%} is false:
            make console execute command "pex user %player% add worldguard.*"
            make console execute command "pex user %player% add worldedit.*"
            execute player command "//pos1"
            execute player command "//pos2" 
            execute player command "//expand {@teren} n"
            execute player command "//expand {@teren} e"
            execute player command "//expand {@teren} s"
            execute player command "//expand {@teren} w"
            execute player command "//expand vert"
            execute player command "rg define %player%"
            execute player command "rg flag %player% greeting &8» &7Wchodzisz na teren gracza &a%player%"
            execute player command "rg flag %player% farewell &8» &7Opuszczasz teren gracza &a%player%"
            execute player command "rg flag %player% creeper-explosion deny"
            execute player command "rg flag %player% mob-damage deny"

            execute player command "rg flag %player% pvp deny"
            execute player command "/rg addowner %player% %player%"
            execute player command "//pos1"
            execute player command "//pos2"
            set {cuboida.%player%} to true
            make console execute command "pex user %player% remove worldguard.*"
            make console execute command "pex user %player% remove worldedit.*"
            make console execute command "pex user %player% add teren.lider"
            wait 1 tick
            loop 99 times:
                send ""
            send "&8» &7Teren zostal zalozony!"
            stop
        else:
            set block to air
            wait 1 tick
            drop 1 jukebox named "&6Zabezpieczenie działki" with lore "&8» Postaw na ziemi, aby użyć" at event-block
            send "&8» &7Już posiadasz dzialke"
 
on mine of jukebox:
        player has permissions "teren.lider":
                make console execute command "rg remove -w %world of player% %player%"
                send "&8» &3Teren zostal usuniety !"
                set {cuboida.%player%} to false
                stop
