PromptPurchaseFinished Firing multiple times

Help and Feedback Scripting Support
1

So I have this server code

game.ReplicatedStorage.PromptPurchase.OnServerEvent:Connect(function(Player, ID)
	MarketplaceService:PromptPurchase(Player, ID)
	MarketplaceService.PromptPurchaseFinished:Connect(function(player, assetId, bought)
		if bought then
			print(player.Name.." purchased "..assetId)
		else
			print(player.Name.." did not purchase "..assetId)
		end
	end)
end)

And this client code

Event = script.Parent.RemoteEvent

SGui = script.Parent
Whole = SGui["Whole frame"]
Top = Whole["top frame"]
Close = Top.close
TryP = Whole.TryOnPants
BuyP = Whole.BuyPants
TryS = Whole.TryOnShirt
BuyS = Whole.BuyShirt

local TryPClick
local BuyPClick
local TrySClick
local BuySClick

Event.OnClientEvent:Connect(function(p1, p2)
	if p1 == "manneq" then
		Tweens.GuiOpen:Play()
		local Model = p2
		
		local Shirt = Model:FindFirstChildOfClass("Shirt")
		local Pants = Model:FindFirstChildOfClass("Pants")
		
		if Shirt then
			TryS.Visible = true
			BuyS.Visible = true
			local ID = Shirt.AssetId.Value
			
			TrySClick = TryS.MouseButton1Click:Connect(function()
				Event:FireServer("try", Shirt)
			end)
			
			BuySClick = BuyS.MouseButton1Click:Connect(function()
				game.ReplicatedStorage.PromptPurchase:FireServer(ID)
			end)
			
		end
		
		if Pants then
			TryP.Visible = true
			BuyP.Visible = true
			local ID = Pants.AssetId.Value

			TryPClick = TryP.MouseButton1Click:Connect(function()
				Event:FireServer("try", Pants)
			end)

			BuyPClick = BuyP.MouseButton1Click:Connect(function()
				game.ReplicatedStorage.PromptPurchase:FireServer(ID)
			end)
			
		end
	end
end)

When I buy a shirt then the server prints out that I bought it. But when I go to buy a second item then the server prints two successful purchase messages and then prints out 3 when I buy the third item. Here is the output I get.

Barty200 purchased 6088610815  -  Server
 ▼ Barty200 purchased 6044721418 (x2)  -  Server
 Barty200 purchased 6044721418
▼ Barty200 purchased 5617933646 (x3)  -  Server
Barty200 purchased 5617933646
Barty200 purchased 5617933646

How do I fix this? Is this a problem with my code?

You keep connecting a new PromptPurchaseFinish everytime you fire the remote. Move the above code out of the ServerEvent connection.
