How to make badge counter?

Badge script counter I tried to make a script that counts players badges, why does it not work?

Error on line 3

wait(2)
for i,v in pairs (game.Players:GetChildren()) do
    if v.userId == plr.PlayerId then
            if game:GetService("BadgeService"):UserHasBadge(plr.userId,229929415) then
                local stat = v.leaderstats:FindFirstChild("Badge")
                if stat ~= nil then
                    stat.Value = stat.Value + 1
                end
            elseif game:GetService("BadgeService"):UserHasBadge(plr.userId,229929797) then
                local stat = v.leaderstats:FindFirstChild("Badge")
                if stat ~= nil then
                    stat.Value = stat.Value + 1
end
end
end
end

thank you
