How can I get the player leaderstats with this script?

Here in the script, when I click on a player the TextLabel and Image becomes a value of the leaderstats, but the problem is that the local hum = target.Parent is looking for the player in the game.workspace, how do I get the local hum = target.Parent to go to game.Players? Is that leaderstats are in game.Players and not game.workspace

local player = game:GetService("Players").LocalPlayer
local mouse = player:GetMouse()
local sc = script.Parent.Holder
local selection = Instance.new("SelectionBox")
selection.Color3 = Color3.fromRGB(255, 0, 0)
selection.Parent = script

mouse.Button2Down:connect(function()
local target = mouse.Target

    if not target then
        selection.Adornee = nil
    else
            local hum = target
            if hum ~= nil then
                    sc.Player.Image = "https://www.roblox.com/Thumbs/Avatar.ashx?x=100&y=100&userId="..hum.UserId --PlayerID
                    sc.Attack.Text = "Attack: "..hum.leaderstats.Attack.Value --leaderstats
                    sc.Agility.Text = "Agility: "..hum.leaderstats.Aggility.Value --leaderstats
                    sc.Defense.Text = "Defense: "..hum.leaderstats.Defense.Value --leaderstats
                    sc.Ki.Text = "Ki: "..hum.leaderstats.Energy.Value --leaderstats
                    sc.Username.Text = ""..hum.Name --PlayerName
        end
    end
end)

Error line 16 userid is not a valid member of part

It's the same as how you accessed the LocalPlayer.

local tag = "xPolarium"

if game.Players[tag] then
	print("Found our desired player.")
end

In your case, you would use the name of hum to locate the player in Players.

Also use Connect over lower case connect as the latter is depricated and is likely to be removed in the future. Good practice to code right than risk anything.
