Prompting a User to Buy Clothes?

For some reason, the user is not prompted to purchase the ID of the clothes I want them to buy. Nothing happens when the button is pressed. What is wrong?

I get an error that TS is not a part of script.Parent, but it is?

local buyButton = script.Parent.SHIRT
local buyButton2 = script.Parent.TextButton
local buyButton3 = script.Parent.TS
player = game.Players.LocalPlayer

buyButton.MouseButton1Click:connect(function()
game:GetService("MarketplaceService"):PromptPurchase(player, 185788753)
end)

buyButton2.MouseButton1Click:connect(function()
game:GetService("MarketplaceService"):PromptPurchase(player, 185788727)
end)

buyButton3.MouseButton1Click:connect(function()
game:GetService("MarketplaceService"):PromptPurchase(player, 184263728)
end)
