Help with alvinblox script please idk what"s happening? [closed]

So I have this alvinblox script

— Leaderboard code which goes inside ServerScriptService, optional to include, you can add your own if you want but bear in mind the gun won’t work unless you have some sort of leaderboard with a Kills and Wipeouts stat

game.Players.PlayerAdded:Connect(function(player)
local leaderstats = Instance.new(“IntValue”,player)
leaderstats.Name = “leaderstats”

local kills = Instance.new(“IntValue”,leaderstats)
kills.Name = “Kills”
kills.Value = 0

local wipeouts = Instance.new(“IntValue”,leaderstats)
wipeouts.Name = “Wipeouts”
wipeouts.Value = 0

— Data saving code goes here if you need it

This was a lengthy tutorial from me, my longest yet! If you want to watch more tutorials on how to script on Roblox, remember to subscribe to my channel.

but it doesn't work, help please thanks
