This works in the testing server but not in the actual game? Its in localScript! Why????

local player = game.Players.LocalPlayer
local currency = player:WaitForChild('leaderstats').Points
local amount = 50
local tool = game.ServerStorage:WaitForChild('BlueKatana')
local indextext = script.Parent.Text
script.Parent.MouseButton1Click:connect(function()
    if currency.Value >= amount and not player.Backpack:FindFirstChild('BlueKatana') or player.Character:FindFirstChild('BlueKatana') then
        currency.Value = currency.Value - amount
        local newtool = tool:Clone()
        newtool.Parent = player.Backpack
    else 
        script.Parent.Text = 'Purchase failed!'
        wait(0.7)
        script.Parent.Text = indextext
    end
end)

script.Parent.MouseEnter:connect(function()
    script.Parent.Parent.Parent.ProductImage.Image = 'rbxassetid://'..script.ImageValue.Value
    script.Parent.Parent.Parent.Description.Text = script.DescValue.Value
    script.Parent.Parent.Parent.ProductTitle.Text = script.TitleValue.Value
end)
script.Parent.MouseLeave:connect(function()
    script.Parent.Parent.Parent.ProductImage.Image = 'rbxassetid://'
    script.Parent.Parent.Parent.Description.Text = ''
    script.Parent.Parent.Parent.ProductTitle.Text = ''
end)
