I am trying to do this but it doesnt work!
Here is my code:

command /saveinventory <string> <string>:
    permission: op
    permission message: "&c&lPCloudMine&r >> &cYou do not have the permissions to execute this command!"
    aliases: /saveinv
    trigger:
        if arg-1 is "save":
            if arg-2 is set:
                if size of {%player's uuid%::%arg-2%::*} - 1 is greater than 0:
                    send "&cError! The inventory %arg-2% is already used!"
                else:
                    loop 35 times:
                        add slot loop-number to {%player's uuid%::%arg-2%::_%loop-number%::*}
                    loop 4 times:
                        add slot loop-number + 100 to {%player's uuid%::%arg-2%::_%loop-number + 100%::*}
                    send "&a&l[✓] &fSaved &7&o%size of {%player's uuid%::%arg-2%::*} - 1%&r&f items."
        if arg-1 is "load":
            if size of {%player's uuid%::%arg-2%::*} - 1 is greater than 0:
                loop 35 times:
                    set slot loop-number of player to {%player's uuid%::%arg-2%::%loop-number%::*}
                loop 4 times:
                    set slot loop-number + 100 of player to {%player's uuid%::%arg-2%::%loop-number + 100%::*}
                send "&a&l[✓] &fFilled your inventory!"
            else:
                send "&cError! The inventory %arg-2% is empty!"
        if arg-1 is "remove":
            if {%player's uuid%.%arg-2%} - 1 is set:
                delete {%player's uuid%.%arg-2%}
                send "&a&l[-] &fRemoved %arg-2%!"
            else:
                send "&cError! The inventory %arg-2% doesn't exist!"
        if arg-1 is "list":
            send {%player's uuid%::*}
            send "&a&l[✓] &fDone!"

i am getting the error in:

                    loop 35 times:
                        add slot loop-number to {%player's uuid%::%arg-2%::_%loop-number%::*}
                    loop 4 times:
                        add slot loop-number + 100 to {%player's uuid%::%arg-2%::_%loop-number + 100%::*}
                    send "&a&l[✓] &fSaved &7&o%size of {%player's uuid%::%arg-2%::*} - 1%&r&f items."

set {item::%player%} to slot 2 of player's inventory

^ this will set the variable to the item in slot 2 of player's inventory.
