Simple chest collector not working!

[HeliumBoi]

​

So I have this code right here that has one error, but I can't find it. ​

Can someone explain ?​

on chest interact:
    if name of event-block is "&6&lCollector":
        set {_chest} to event-block
        set {_inv} to inventory of {_chest}
        set {_balance} to balance of player
        set {_totalWorth} to 0
        loop 53 times:
            set {_item} to item from {_inv} at slot loop-number
            if {_item} is not air:
                if worth of {_item} is set:
                    set {_value} to worth of {_item}
                    set {_num} to {_item}'s amount
                    remove {_num} {_item} from {_inv}
                    set {_totalWorth} to {_totalWorth} + ({_value} * {_num})
                    set {_balance} to {_balance} + ({_value} * {_num})
                    send "&aSold %{_num}% x %{_item}% for %{_value}%."
        set balance of player to {_balance}
        send "&aTotal worth: %{_totalWorth}%."

command /chestgive:
    permission: myplugin.chestgive
    aliases: [givechest]
    trigger:
        give player a chest named "&6&lCollector"
        send "&aYou have been given a &6&lCollector chest!"

on rightclick on chest:
    if name of event-block is "&6&lCollector":
        set {_chest} to event-block
        set {_inv} to inventory of {_chest}
        set {_balance} to balance of player
        set {_totalWorth} to 0
        loop 53 times:
            set {_item} to item from {_inv} at slot loop-number
            if {_item} is not air:
                if worth of {_item} is set:
                    set {_value} to worth of {_item}
                    set {_num} to {_item}'s amount
                    remove {_num} {_item} from {_inv}
                    set {_totalWorth} to {_totalWorth} + ({_value} * {_num})
                    set {_balance} to {_balance} + ({_value} * {_num})
                    send "&aSold %{_num}% x %{_item}% for %{_value}%."
        set balance of player to {_balance}
        send "&aTotal worth: %{_totalWorth}%."

command /chestgive:
    permission: myplugin.chestgive
    aliases: [givechest]
    trigger:
        give player a chest named "&6&lCollector"
        send "&aYou have been given a &6&lCollector chest!"
