Script not checking player's cash, How to fix?

Hello. So im trying to make a script to make the player upgrade his Bread Factory. but when i click the button it does not work! The build part works (to build the bread factory) but the upgrade part not. it doesnt check player stats for some reason (Cash).

local model1 = script.Parent.Parent.Parent.brick1
local Upgradecost = 0
local MoreCash = script.CC.Value
local factory = script.Parent.Parent.Parent
local isUpgrading = false
model1.Parent = game.Lighting
local model = game.Lighting.brick1
wait()

script.Parent.ClickDetector.MouseClick:Connect(function(poeple)
	if poeple.Name == factory.OwnerName.Value then
		if isUpgrading == false then
					if game.Players:FindFirstChild(poeple.Name).leaderstats.Cash.Value >= Upgradecost then
			game.Players:FindFirstChild(poeple.Name).leaderstats.Cash.Value = game.Players:FindFirstChild(poeple.Name).leaderstats.Cash.Value - Upgradecost
			model.Parent = workspace
			game.Players:FindFirstChild(poeple.Name).PlayerGui.bred.Enabled = true
				isUpgrading = true
				Upgradecost = 5
				script.Parent.SurfaceGui.TextLabel.Text = "Upgrade-$".. Upgradecost
			end
		else
if game.Players:FindFirstChild(poeple.Name).leaderstats.Cash.Value >= Upgradecost then -- error is here
	Upgradecost = Upgradecost * math.random(2,3)
					script.Parent.SurfaceGui.TextLabel.Text = "Upgrade-$".. Upgradecost
				game.Players:FindFirstChild(poeple.Name).leaderstats.Cash.Value = game.Players:FindFirstChild(poeple.Name).leaderstats.Cash.Value - MoreCash
			else
				print("oof")
					end
				end
		end


end)

it keeps printing 'oof' (i added that so i could know if its because of the stat) It should increase the price when upgrading
