Region3 not working even though im in the region?

local R3 = Region3.new(Vector3.new(73, -math.huge, -85.5), Vector3.new(-71.5, math.huge, -224))
local humrootpart = {}

game.Players.PlayerAdded:Connect(function(plr)
    plr.CharacterAdded:Connect(function(char)
		table.insert(humrootpart, char.HumanoidRootPart)
		print(#humrootpart)
    end)
end)

while wait() do
	if humrootpart then
	print(#(workspace:FindPartsInRegion3WithWhiteList(R3, humrootpart, math.huge)))
        for _,touch in 		 pairs(workspace:FindPartsInRegion3WithWhiteList(R3,humrootpart,math.huge)) do
               print("touched")
        end
    end
end

It doesn't recognize i'm in the region 3, the print "print(#(workspace:FindPartsInRegion3WithWhiteList(R3, humrootpart, math.huge)))" prints 0 even when i'm 100% in the region. If anyone knows what I did wrong here please let me know.

	local R3 = Region3.new(Vector3.new(73, -math.huge, -85.5), Vector3.new(-71.5, math.huge, -224))

Thats the problem

The first parameter wants the smallest Vector3 amongst the 2 (The one on the bottom left lower corner) and then the second paramater wants the biggest (The one on the Top right upper corner)

So it should be written like this instead :

local R3 = Region3.new(Vector3.new(-71.5, -200, -224), Vector3.new(73, 200, -85.5))

Edited : U cant use math.huge for region3
