Why isn't PriceInTickets working?

The PriceInRobux is working but not PriceInTickets(Line 40),why? If you need the model its here http://www.roblox.com/Help-item?id=159979067

NameOfProduct = 159913543
Item = game:GetService("MarketplaceService"):GetProductInfo(NameOfProduct)-- Gets the service Markplace
part = script.Parent
Product = script.Parent.Parent.product
clicked = false
part.MouseButton1Click:connect(function()
---------------Debounce------------------
 if clicked == false--Checks if clicked is false(Which it should be,because it already been set false)
    then 
    clicked = true-- Since it false it will turn it true(so we know it's already been clicked)

----------------Fade Out------------------
    for fo = 0,10 do
        wait(0.1)
        part.BackgroundTransparency = fo/10--You need to divide to get the precise number(Other way won't work)
        part.TextTransparency = fo/10
        if fo/10 ==1
            then
            part.Visible = false
            clicked = false --Turns it false,so it you won't able to click it.
         Product.Visible = true
--------------The frame--------------------
 Product:TweenSize(UDim2.new(0, 700,0, 500),"Out","Sine",1,true)--The animation
-------------MarketPlace Service-----------
Product.ProductImage.Thumbnail.Image = "http://www.roblox.com/Game/Tools/ThumbnailAsset.ashx?aid="..NameOfProduct.."&fmt=png&wd=420&ht=420"--Gets the thumbnail of the product
Product.ProductName.Text = Item.Name--Gets name of item
Product.ProductDescription.Text = "Description"..": "..Item.Description--Gets Description of item
Product.ProductRobux.Text = Item.PriceInRobux--Gets the price of Robux
------------Removes Nulls-----------------
if Product.ProductRobux.Text == "null" -- No one likes them
    then
     Product.RLabel.Visible = false
    Product.ProductRobux.Visible = false
elseif Product.ProductRobux.Text == "null"
    then
    Product.RLabel.Visible = true
    Product.ProductRobux.Visible = true
-------------------------------------------
print(Item.PriceInTickets)
Product.ProductTix.Text = Item.PriceInTickets--Gets the price of tix
------------Removes Nulls-----------------
if Product.ProductTix.Text == "null"
    then
    Product.ProductTix.Visible = false
    Product.Tixlabel.Visible = false
elseif Product.ProductTix.Text == "null"
    then
    Product.Tixlabel.Visible = true
    Product.ProductTix.Visible = true
