Can someone help with putting 2 "for loops" inside another?

This script is a server-script, inside of my StarterCharacter scripts. I know that HopperBin is deprecated, but I just found a server-script from the Roblox library that kicked anyone that had it, and it worked. But I want to be more specific on the BinType so . . .

This is my code so far. The code may look broken off so just look at the source:

local BtoolTypes = {"Hammer", "Clone", "Grab"}

while true do
	wait(10)
	for i, v in 
pairs(game:GetService("Players"):GetPlayerFromCharacter(script.Parent).Backpack:GetChildren()) do
		if v:IsA("HopperBin") then
			for i = 1, #BtoolTypes do
				if v.BinType == BtoolTypes[i] then
					game:GetService("Players"):GetPlayerFromCharacter(script.Parent):Kick()
				end
			end
		end
	end	
end

Can anyone help?
