Why is there a W006 warning in this developer-products script?

So, in this developer product purchasing server-sided handler, there is a warning on line 17 W006 warning in my script, how to get it away?

This is what the warning says:

"W006: Statement spans multiple lines; use indentation to silence"

Here is my coding:

(Also, is there something else that I did wrong with this script? , the MarketplaceService-part should fire when the player buys a dev product via my GUI)

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

local MarketplaceService = game:GetService("MarketplaceService")
local productId1 = 43143055 --//200 snowflakes
local productId2 = 43143018 --//500 snowflakes
local productId3 = 43143112 --//1000 snowflakes
local productId4 = 43143148 --//5000 snowflakes

--MarketplaceService.ProcessReceipt will fire when someone completes a purchase, This is how it runs!
MarketplaceService.ProcessReceipt = function(receiptInfo) 
    -- find the player based on the PlayerId in receiptInfo
    for i, player in ipairs(game.Players:GetChildren()) do
        if player.userId == receiptInfo.PlayerId then
            -- check which product was purchased
            if receiptInfo.ProductId == productId1 then 
				player.leaderstats.Snowflakes.Value = (player.leaderstats.Snowflakes.Value + 200)
			elseif receiptInfo.ProductId == productId2 then 
				player.leaderstats.Snowflakes.Value = (player.leaderstats.Snowflakes.Value + 500)
			elseif receiptInfo.ProductId == productId2 then 
				player.leaderstats.Snowflakes.Value = (player.leaderstats.Snowflakes.Value + 1000)
			elseif receiptInfo.ProductId == productId2 then 
				player.leaderstats.Snowflakes.Value = (player.leaderstats.Snowflakes.Value + 5000)
            end
        end
    end	

	-- record the transaction in a Data Store
	local playerProductKey = "player_" .. receiptInfo.PlayerId .. "_purchase_" .. receiptInfo.ProductId
	ds:IncrementAsync(playerProductKey, 1)	
 
	-- tell ROBLOX that we have successfully handled the transaction
	return Enum.ProductPurchaseDecision.PurchaseGranted		
end

Any help is greatly appreciated!

Identation means that it wants you to add extra whitespace. tab.

Part.Position = Vector3.new(
0,
0,
0
)

or

Part.Position = Vector3.new(
	0,
	0,
	0
)

##1 will give the warning, #2 will not.
