Data table not saving??

I've been trying to get one data store to save multiple values by using a table, but it's not working. Every time I leave and rejoin, none of the values load back. I have no idea what i'm doing wrong so I really need help solving this bug.

game.Players.PlayerAdded:connect(function(player)
	
	
 local leader = Instance.new("Folder",player)
 leader.Name = "leaderstats"

 local Cash = Instance.new("IntValue",leader)
 Cash.Name = "Cash"
	Cash.Value = 0


 local XP = Instance.new("IntValue",leader)
 XP.Name = "XP"
	XP.Value = 0

 local Lvl = Instance.new("IntValue",leader)
 Lvl.Name = "Lvl"
	Lvl.Value = 1

local EquippedKnife = Instance.new("StringValue", player)
EquippedKnife.Name = "EquippedKnife"
	EquippedKnife.Value = "Default"

local EquippedGun = Instance.new("StringValue", player)
EquippedGun.Name = "EquippedGun"
	EquippedGun.Value = "Default"

local playerData = ds:GetAsync(tostring(player.UserId))

if playerData ~= nil then
	Cash.Value = playerData[1] 
	XP.Value = playerData[2] 
	Lvl.Value = playerData[3] 
	EquippedKnife.Value = playerData[4] 
	EquippedGun.Value = playerData[5] 
	end
end)



game.Players.PlayerRemoving:connect(function(player)
	 ds:SetAsync(tostring(player.UserId),
	{
	player.leaderstats.Cash.Value,
	player.leaderstats.XP.Value,
	player.leaderstats.Lvl.Value,
	player.EquippedKnife.Value,
	player.EquippedGun.Value
	})
end)
