Need help with this 2x gamepass? Keeps on multiplying.

	
	local marketservice = game:GetService("MarketplaceService")
	
	local can = true
	repeat wait() until player:FindFirstChild("leaderstats")
	local leader = player:FindFirstChild("leaderstats")
	if leader then
	repeat wait() until leader:FindFirstChild(script:WaitForChild("Currency").Value)
	local currency = leader:FindFirstChild(script:WaitForChild("Currency").Value)
		if currency then
			local folder = Instance.new("Folder",player)
			folder.Name = "2xGamepass"
			local oldmoney = Instance.new("IntValue",folder)
			oldmoney.Name = "OldMoney"
			oldmoney.Value = currency.Value
			local give2x = Instance.new("IntValue",folder)
			give2x.Name = "Give2x"
			give2x.Value = 0
			
			currency.Changed:Connect(function()
				if marketservice:UserOwnsGamePassAsync(player.UserId, script:WaitForChild("GamepassId").Value) then
				
					
				if can == true then
					can = false
				if currency.Value > oldmoney.Value then
				give2x.Value = currency.Value - oldmoney.Value
			
				currency.Value = currency.Value + give2x.Value
				
				oldmoney.Value = currency.Value
					can = true
					else
						
							oldmoney.Value = currency.Value
							can = true
						
						
				end
					
				end
				else
					oldmoney.Value = currency.Value
				end
			end)
			
		end
	end
end)```


Everytimee when you leave and rejoin, your kills multiplies, then you keep getting2x the coins every kill you get, pls help me.

If the gamepass only intends to give you 2x kills once, you will need to set up a datastore to check if its been done. If you need the kills and 2x coins to only be active once, look into developer products.
