How can I make it so this command doesn't break when a kick reason isn't provided?.

Good afternoon,

I am making an admin system, and I want to know how I can make this command not break when a reason isn't provided.

:kick me should work

:kick me Bye should also work.

local Owners = {"", ""}
local SuperAdmins = {"", ""}
local Administrators = {"", ""}
local Moderators = {"", ""}
local Banlist = {"", ""}
local BanMessage = ""
local Prefix = ":"

local KickCommand = Prefix.."kick "
local FireCommand = Prefix.."fire "

game.Players.PlayerAdded:Connect(function(p)
	local AdminLevel = Instance.new("Folder", p)
	AdminLevel.Name = "AdminLevel"
	local AdminValue = Instance.new("IntValue", AdminLevel)
	AdminValue.Name = "AdminValue"
	AdminValue.Value = 0
	
	for i,v in pairs(Banlist) do
		if p.Name == v then
			p:Kick(BanMessage)
		end
	end
	
	for i,v in pairs(Moderators) do
		if p.Name == v then
			p.AdminLevel.AdminValue.Value = 1
		end
	end
	
	for i,v in pairs(Administrators) do
		if p.Name == v then
			p.AdminLevel.AdminValue.Value = 2
		end
	end
	
	for i,v in pairs(SuperAdmins) do
		if p.Name == v then
			p.AdminLevel.AdminValue.Value = 3
		end
	end
	
	for i,v in pairs(Owners) do
		if p.Name == v then
			p.AdminLevel.AdminValue.Value = 4
		end
	end
	
	if p.UserId == game.CreatorId then
		p.AdminLevel.AdminValue.Value = 5
	end
	
	if p.AdminLevel.AdminValue.Value >= 1 then
		p.Chatted:Connect(function(msg)
			local arguments = string.split(msg, " ")
			if arguments and arguments[2] then
				if arguments[1] == KickCommand then
					local name = (arguments[2] == "me" and p.Name) or arguments[2]
					local reason = arguments[3] and arguments[3] or "Unspecified reason."
					local full = game.Players:GetPlayers()
					print(name)
					local player = game.Players:FindFirstChild(name)
					if player then
						player:Kick("Kicked by: "..p.Name..". Reason: "..reason)
					else
						local clone = script.Error:Clone()
						clone.Parent = p.PlayerGui
						clone.Frame.TextLabel.Text = "Error: Player(s) is not in game!"
						wait(2)
						clone:Destroy()
					end
				end
			end
		end)
	end
end)

Any suggestions or ideas?

something like and it should work:

local admins  = require("directory of module name 'admin' ")
local Players = game:GetService("Players")


Players.PlayerAdded:Connect(function(player)
    for _, admin in pairs(admins) do
        if(admin:lower() == player.Name:lower()) then
            player.Chatted:Connect(OnChatted)
        end
    end
end)


function OnChatted(msg)
    local command, playerName, kickMessage = msg:match("^:([%w]+)%s([%w]+)%s?(.*)")

    if(command and command == "kick" and playerName) then
        for _, player in pairs(Players:GetPlayers()) do
            if(player.Name:lower() == playerName:lower()) then
                player:Kick(kickMessage)
            end
        end
    end
end
