For some reason the kick script I just made won't work. Anyone have solutions? (ANSWERED)

I just made a kick script, and nothing happened in output and it didn't kick me. (I said in the chat /e kick FrostedFlakes67). Here's the code, I hope someone can help.

game:GetService("Players").PlayerAdded:Connect(function(plr)
	if plr.UserId == game.CreatorId then
		plr.Chatted:Connect(function(msg)
			local lowermsg = string.lower(msg)
			local command = "/e kick "
			if string.sub(lowermsg,1,#command) == command then
				local PlayerToKick = string.sub(msg,#command,#lowermsg)
				game:GetService("Players"):FindFirstChild(PlayerToKick):Kick("You have been kicked from the game by the game's owner.")
			end
		end)
	end
end)

You people are so complicated- #function this,creator.id that. all you need is a detect, then variable finding the name. Like this, put it in a normal script in workspace!

--Tested and worked

game:GetService("Players").PlayerAdded:Connect(function(plr)
    if plr.UserId == game.CreatorId then
        plr.Chatted:Connect(function(msg)
            if string.sub(msg,1,8) == "/e kick " then
                local PlayerToKick = string.sub(msg,9)--if you dont know btw, just puttin begin makes it from that character all the way to the end
                game.Players:FindFirstChild(PlayerToKick):Kick("You have been kicked from the game by the game's owner.")
            end
        end)
    end
end)

After looking carefully, I figured out that there was a space before the player's name, so it was trying to kick " FrostedFlakes67". I just fixed it by doing #command+1, and it is now working, but I changed up the script a lot, and put it as a free model. Here is the model: https://web.roblox.com/catalog/03255077426/redirect Here is the new script:

--People using this script: Do not edit this unless you know what you are doing, this will not work if the game is not published, read "README" for instructions.
game:GetService("Players").PlayerAdded:Connect(function(plr)
	print("Player has joined!")
	if plr.UserId == game.CreatorId then
		print("Player is owner!")
		plr.Chatted:Connect(function(msg)
			print("Player has chatted!")
			local lowermsg = string.lower(msg)
			local command = "/e kick "
			if string.sub(lowermsg,-1,#command) == command then
				warn("Owner is kicking someone!")
				local PlayerToKick = string.sub(msg,#command+1,#lowermsg)
				print("Player to kick is: "..PlayerToKick)
				game.Players:FindFirstChild(PlayerToKick):Kick("You have been kicked from the game by the game's owner.")
				warn("Owner kicked "..PlayerToKick.."!")
			end
		end)
	end
end)

Thanks for all the support!
