What is broken in this dev purchase script?

So I posted part of this code before where I had the 2 ends missing but now that I've finished it it still doesn't seem to work.

local MarketplaceService = game:GetService("MarketplaceService")
local ds = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
  
ID1 = 33445219 -- (5K) ID hawn
local ID1_Reward = 5000 -- ir-Reward hawn
ID2 = 33445422 -- (25K)
local ID2_Reward = 25000
ID3 = 33445463 -- (50K)
local ID3_Reward = 50000
ID4 = 33445512 -- (100K)
local ID4_Reward = 100000

MarketplaceService.ProcessReceipt = function(receiptInfo)
	local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_product_" .. receiptInfo.ProductId
	local numberBought = ds:IncrementAsync(playerProductKey, 1)
	for i,v in pairs (game.Players:GetChildren()) do
		--ID 1
		if v.userId == receiptInfo.PlayerId then
			if receiptInfo.ProductId == ID1 then
				local lds = game.ServerStorage:WaitForChild("PlayerMoney")
				if lds ~= nil then
					local cs = lds:FindFirstChild(v) 
					if cs ~= nil then
						cs.Value = cs.Value + ID1_Reward
					end
				end
			end
		end	
				
		--ID 2
		if v.userId == receiptInfo.PlayerId then
			if receiptInfo.ProductId == ID2 then
				local lds = game.ServerStorage:WaitForChild("PlayerMoney")
				if lds ~= nil then
					local cs = lds:FindFirstChild(v) 
					if cs ~= nil then
						cs.Value = cs.Value + ID2_Reward
					end
				end
			end
		end
			
		--ID 3
		if v.userId == receiptInfo.PlayerId then
			if receiptInfo.ProductId == ID3 then
				local lds = game.ServerStorage:WaitForChild("PlayerMoney")
				if lds ~= nil then
					local cs = lds:FindFirstChild(v) 
					if cs ~= nil then
						cs.Value = cs.Value + ID3_Reward
					end
				end
			end
		end	
					
		--ID 4
		if v.userId == receiptInfo.PlayerId then
			if receiptInfo.ProductId == ID4 then
				local lds = game.ServerStorage:WaitForChild("PlayerMoney")
				if lds ~= nil then
					local cs = lds:FindFirstChild(v) 
					if cs ~= nil then
						cs.Value = cs.Value + ID4_Reward
					end
				end
			end
		end																	
	end
	return Enum.ProductPurchaseDecision.PurchaseGranted		
end
