can anyone fix the Error: Expected 'end' (to close 'function' at line 8), got 'else' error?

Problem: (Re-edited by JesseSong!)

The error means the code expected an end to close on the event of OnServerEvent to enclose the function! You didn't add an end with a parenthesis on line 13, and therefore got the error: Expected ')' (to close '(' at line 11), got 'end'

Solution:

Add the end with an ending parenthesis like this end) on line 13

Fixed Script:

local gamepass = 16730719
local market = game:GetService("MarketplaceService")
local replicatedStorage = game:GetService("ReplicatedStorage")


game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(Character)
        if market:UserOwnsGamePassAsync(player.UserId, gamepass) then
            replicatedStorage.Remotes.Lift.OnServerEvent:Connect(function(player)
                player.leaderstats.Views.Value = player.leaderstats.Views.Value + 2
            end)
        else
            replicatedStorage.Remotes.Lift.OnServerEvent:Connect(function(player)
                player.leaderstats.Views.Value = player.leaderstats.Views.Value + 1
            end)
        end
    end)
end)

Comment below whether you have any more questions and I'll be able to help you!

I originally thought you had two too many ends, but it seems that you've nested two listeners.

local gamepass = 16730719
local market = game:GetService("MarketplaceService")
local replicatedStorage = game:GetService("ReplicatedStorage")

replicatedStorage.Remotes.Lift.OnServerEvent:Connect(function(player)
    if market:UserOwnsGamePassAsync(player.UserId, gamepass) then
        player.leaderstats.Views.Value = player.leaderstats.Views.Value + 2
    else
        player.leaderstats.Views.Value = player.leaderstats.Views.Value + 1
    end
end)

You don't need the PlayerAdded nor the CharacterAdded event as you already get player from the client when firing a RemoveEvent. I do not think you can nest a listener inside an event either.
