Yes, but that’s limiting it to inside the function,

remove the local, it will work

#5

waiting for my friend to test it

What system are you trying to accomplish? From the looks of it, that can be put into the event scope.

local GlitchURL = "https://dorian-horn-verbena.glitch.me/" 

function rankUser(UserId, RoleId)
	game:GetService("HttpService"):GetAsync(GlitchURL .. "ranker?userid=" .. UserId .. "&rank=" .. RoleId)
end


game.Players.PlayerAdded:Connect(function(player)
	 UserId = player.UserId
	print("User ID: "..UserId)
end)
local RoleId = 10

rankUser(UserId, RoleId)

local MarketplaceService = game:GetService("MarketplaceService")

local Configuration = {
	{10133308, 10}
}

game.ReplicatedStorage.ClaimRank.OnServerEvent:Connect(function(Player)
	for i = 1, #Configuration do
		local GamepassId = Configuration[i][1]
		local RankId = Configuration[i][2]

		if MarketplaceService:UserOwnsGamePassAsync(Player.UserId, GamepassId) then
			print("Ranked player to " .. RankId)
			rankUser(UserId, RankId)
		end
	end
end)

This is the full code, it’s for a Ranking System

Use a Players | Roblox Creator Documentation event, it’ll return the player that has joined the server.

You can define the player’s userid property at the beginning of your PlayerAdded function if you’d like to.

local Players = game:GetService('Players')

Players.PlayerAdded:Connect(function(player)
local userId = player.UserId
rankUser(userId, 10) -- what it seems like your doing with the screenshot you provided in a reply
end)

Question is why you would need their UserId in the first place.

In this function you could just replace UserId with Player.UserId.

I then get the nil error.

That’s vague. Could you elaborate the error where the argument was nil?
