My Premium Nametag doesn't work?

Hi! PlayerHasPass is no longer supported by ROBLOX, use UserOwnsGamePassAsync instead, same with MarketplaceService, rather than GamepassService. player is also no longer a valid parameter, use player.UserId instead.

Your script should be:

local id = 1082986441
local billboardgui = script:WaitForChild("BillboardGui")

game.Players.PlayerAdded:connect(function(player)
    if game:GetService("MarketplaceService"):UserOwnsGamePassAsync(player.UserId, id) then 
      local b = billboardgui:Clone()
b.Parent = game:GetService("Players").LocalPlayer.Character
    else
        print(player.Name .. " doesn't have the game pass...")
    end
end)

Hope this works!

The PlayerHasPass method is broken because of the new game pass updates. As previously mentioned, MarketplaceService:UserOwnsGamePassAsync() should be used instead. Another problem is you were using LocalPlayer from a server script, which LocalPlayer is nil on. Since you were using PlayerAdded, use its parameter instead.

wait()
local Players = game:GetService("Players")
local MarketplaceService = game:GetService("MarketplaceService")
local id = 1082986441
local billboardgui = script.BillboardGui

local function hasPass(plr)
    return MarketplaceService:UserOwnsGamePassAsync(plr.UserId, id)
    -- return true if they have the id, return false if not 
end

game.Players.PlayerAdded:Connect(function(player) -- :connect is deprecated, use :Connect. also, this is the player, use this and not LocalPlayer
    player.CharacterAdded:Connect(function(character) -- wait for character! 
        if hasPass(player) then -- if they have the pass
            local b = billboardgui:Clone()
            b.Parent = character
        else
            print(player, "doesn't have the game pass...")
        end
    end)
end)

Hello, AzbenNR!

local id = 1082986441
local billboardgui = script:WaitForChild("BillboardGui")

game.Players.PlayerAdded:connect(function(player)
    if game:GetService("GamePassService"):PlayerHasPass(player, id) then
      local b = billboardgui:Clone()
      b.Parent = player.Character
      b.Parent.Position = player.Character.Head.Position + Vector3.new(0, 1, 0) -- Sets the bilboard gui position at the player's head position(with a offset)
    else
        print(player.Name .. " doesn't have the game pass...")
    end
end)

(To make the bilboard gui be shown to all players, just plcae the script on a normal script)

Good Luck with your games
