I'm trying to make it so when my mouse hovers over a object my GUI appears it no work?

 local UIS = game:GetService("UserInputService")
local pickupKey = "e"

local player = game.Players.LocalPlayer 
local mouse = player:GetMouse()

local PlayerGui = player:WaitForChild("PlayerGui")
local PickupInfoGui = PlayerGui:WaitForChild("PickupInfoGui")

UIS.InputChanged:Connect(function(input)
    if mouse.Target then
        if mouse.Target:FindFirstChild("Pickable") then
            local item = mouse.Target
            PickupInfoGui.Adornee = item
            PickupInfoGui.ObjectName.Text = item.Name
            PickupInfoGui.Enabled = true
        else
            PickupInfoGui.Adornee = nil
            PickupInfoGui.Enabled = false
        end
    end
end)

There is my code.
