How can I make dev product menu

I have made a dev product button which works and all but when I want to add specific values which belong to each of the button it wont let me because I can’t send over the value that I want to add to the server so help

local MarketplaceService = game:GetService("MarketplaceService")
 
local function processReceipt(receiptInfo,Player,Amount)
 
	-- Find the player who made the purchase in the server
	local player = game:GetService("Players"):GetPlayerByUserId(receiptInfo.PlayerId)
	if not player then
		-- The player probably left the game
		-- If they come back, the callback will be called again
		return Enum.ProductPurchaseDecision.NotProcessedYet
	end
 
	-- Output what product they bought
 	player.Coins.Value = player.Coins.Value + Amount
	-- IMPORTANT: Tell Roblox that the game successfully handled the purchase
	return Enum.ProductPurchaseDecision.PurchaseGranted
end
 
-- Set the callback (this can only be done once by one script on the server!)
MarketplaceService.ProcessReceipt = processReceipt

Amount is the value im trying to add

ProcessReceipt is called internally with a dictionary dubbed the receipt of the purchase and that is the only parameter that you can have for ProcessReceipt. Everything else that you do is based off of this - from fetching the player, to determining what was bought and looking for the proper handler for the product and so on.

The ProcessReceipt page has a good example of how you can make something like this; as in, adding a certain amount of cash to a player’s data based on what product they purchased. I would advise you to look through there for an example of how to achieve this.
