I have a script but it doesnt work, how can I get it to work with Filtering Enabled?

CORRECTION: The script does work, but how can I get it to display the GUI right next to the mouse, and display their rank in a group as well?

local Player=game.Players.LocalPlayer
local gui = script.Parent.Frame

repeat wait() until Player and Player.Character and wait(5)

local Character=Player.Character
local mouse=Player:GetMouse()
local hoverPlayer = false

mouse.Move:connect(function()
    if mouse.Target ~= nil then
        local humanoid, player = mouse.Target.Parent:findFirstChild("Humanoid"), game.Players:FindFirstChild(mouse.Target.Parent.Name)
        if humanoid and player then
            if not hoverPlayer then
                gui.NameLabel.TextColor3 = player.TeamColor.Color
                gui.NameLabel.Text = humanoid.Parent.Name
                gui.HealthLabel.Text = math.ceil(mouse.Target.Parent.Humanoid.Health / mouse.Target.Parent.Humanoid.MaxHealth * 100) .."%" 
                hoverPlayer = true      
            end
        else
            hoverPlayer = false     
            gui.NameLabel.Text = ""
            gui.HealthLabel.Text = ""
        end
    end
end)
