end expected to close function?

i maded a question like 8 hours ago and it seems to have worked.. BUT however it is STILL broken!

the full script:

--//Admin Commands Script
--//Variables\\--
local DataStore = game:GetService("DataStoreService")
local BanList = DataStore:GetDataStore("BanList")
local Admins = {"no, i wont give u free admin"} --//admins

--//Events\\--
game.Players.PlayerAdded:connect(function(Player)
    local Folder = Instance.new("Folder", Player)
    Folder.Name = "PlayerValues"

    local BanCheck = Instance.new("BoolValue", Folder)
    BanCheck.Name = "IsBanned"
    BanCheck.Value = BanList:GetAsync(Player.userId) or false --//False is default if no save for the player

--//Checks if the player is banned or not
if Player.PlayerValues.IsBanned.Value == true then
    Player:Kick("You're Banned From This Game.") --//Reason for kick
end

Player.Chatted:connect(function(message)
    for i, AdminName in ipairs(Admins) do
        if Player.Name == AdminName then
            --//Commands\\--
            --//Kill Command
            if message:sub(1, 6) == "/kill " then
                local TargetPlayer = game.Players:FindFirstChild(message:sub(7))
                if TargetPlayer then
                    local Character = TargetPlayer.Character
                    if Character then
                        Character.Humanoid.Health = 0
                    end
                end
            end

                --//Heal Command
                if message:sub(1, 6) == "/heal " then
                    local TargetPlayer = game.Players:FindFirstChild(message:sub(7))
                    if TargetPlayer then
                        local Character = TargetPlayer.Character
                        if Character then
                            Character.Humanoid.Health = Character.Humanoid.MaxHealth
                        end
                    end
                end

                --//Kick Command
                if message:sub(1, 6) == "/kick " then
                    local TargetPlayer = game.Players:FindFirstChild(message:sub(7))
                    if TargetPlayer then
                        TargetPlayer:Kick("Kicked by " .. Player.Name) --//Kick message/reason
                    end
                end

                --//Ban Command
                if message:sub(1, 5) == "/ban " then
                    local TargetPlayer = game.Players:FindFirstChild(message:sub(6))
                    if TargetPlayer then
                        local BanCheck = TargetPlayer.PlayerValues.IsBanned
                        if BanCheck then
                            BanCheck.Value = true
                            BanList:SetAsync(TargetPlayer.userId, true)
                        end
                        TargetPlayer:Kick("You've been banned from this game by " .. Player.Name) --//Reason || Message
                    end
                end

                --//Unban Command
                if message:sub(1, 7) == "/unban " then --//USES ID NOT NAME
                    local UserId = tonumber(message:sub(8))
                    if UserId then
                        BanList:SetAsync(UserId, false)
                    end
                end
            --//im cencoring this command xdd

                        end)
                break
            end
        end
    end
        end
    end)

the problem is at line 8, when i place end it breaks other parts.
