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
