i have multiple folders that i want to look through to check the price and print the lowest price a.k.a the attribute for every pad

local function findcheapestpad(tycoon)
	local minvalue = math.huge
	
	for _, pad in tycoon:FindFirstChild("Pads"):GetChildren() do
		if pad:GetAttribute("Price") < minvalue then
			minvalue = pad:GetAttribute("Price")
		end
	end
	
	for _, pad in tycoon:FindFirstChild("BoughtItems"):GetChildren() do
		if pad:HasTag("Pad") then
			print(pad)
			if pad:GetAttribute("Price") < minvalue then
				minvalue = pad:GetAttribute("Price")
			end
		end
	end
	
	return minvalue
end

I have tried doing this but after getting to the builds folder it just returns inf

Are you sure “pad” has the price attribute or not or the “Pad” tag?

#3

okay it works now thanks for helping i figured it out

local function findcheapestpad(tycoon)
	local minvalue = math.huge
	
	for _, pad in tycoon:FindFirstChild("Pads"):GetChildren() do
		if pad:GetAttribute("Price") < minvalue then
			minvalue = pad:GetAttribute("Price")
		end
	end
	
	for _, build in tycoon:FindFirstChild("BoughtItems"):GetChildren() do
		for _, pad in build:GetChildren() do
			if pad:HasTag("Pad") then
				print(pad)
				if pad:GetAttribute("Price") < minvalue then
					minvalue = pad:GetAttribute("Price")
				end
			end
		end
	end
	
	return minvalue
end

i just had to make another for loop

another question though should i break the loop? i never break loops if i’m being honest :grin:

#4

Oh so it didn’t in-fact exist okay… And no, no need to break loops. Unless you are going to call them every 60 seconds and the loop is big.

#5

okay i remember seeing someone break a loop if something is nil i assume to avoid errors

#6

Yeah but no need for this one.
