Need help making a Pay To Re-spawn script for my upcoming horror game?

Hello,

I am currently trying to make a pay to re-spawn script for my horror game. However, i'm having a lot of difficulty.

What is meant to happen is when you die, you would get prompted a message asking if you would like to re-spawn for a sum of ROBUX through DevProducts and if you do not decide to re-spawn, you get teleported back to the start game,

So far I have, But my scripting knowledge todo with DevProducts is confusing.

local mps = game:GetService("MarketplaceService")
local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")

mps.ProcessReceipt = function(receiptInfo) 
	for i, player in pairs(game.Players:GetChildren()) do
		if player.userId == receiptInfo.PlayerId then
			if receiptInfo.ProductId == 629857448 then
			print("yay")
			else
		game.Players.PlayerAdded:Connect(function(player)
			player.CharacterAdded:Connect(function(char)
			player:Kick("I tried, I tried...")
			print("oof")
			end)
			end)		
			end
		end
	end	

	local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_purchase_" .. receiptInfo.ProductId
	ds:IncrementAsync(playerProductKey, 1)	

	return Enum.ProductPurchaseDecision.PurchaseGranted
end
