Overhead Gui Remains Unchanged - Help?

Hello, everyone.

I'm trying to create a custom rigged humanoid that displays the Name and Level value of the NPC above it's appearance. However, the Text has remain unchanged whenever i test it in Studio and in server. Here is the Local Script that i have inside the TextLabel. (TextLabel is named "Desc" btw.)

local class = script.Parent.Parent.Parent.Humanoid.Name
local level = script.Parent.Parent.Parent.Level

repeat wait()
    script.Parent.Parent.Desc.Text = class .. "  Lv. " ..level.Value
until
    script.Parent.Parent.Desc.Text == class .. "  Lv. " ..level.Value

level.Changed:connect(function()
    script.Parent.Parent.Desc.Text = class .. "  Lv. " ..level.Value
end)

All suggestions and recommendations are welcome! Thank you, for your time.
