Both Costume Health and Humanoid-Health Regeneration Doesnt Work!?

So i was making my game when i ran into an unexpected proplem that wasnt even in error log

anway

Experimental mode : off Filtering enabled = on

my code for costume health

local plr = game.Players.LocalPlayer

plr.CharacterAdded:Connect(function(character)
local Humanoid = plr.Character:WaitForChild("Humanoid")
local HG = script.Parent
local Text = HG:WaitForChild("Back"):WaitForChild("Text")
local hlth = Humanoid.Health
local mxhlth = Humanoid.MaxHealth


Humanoid.Health.Changed:Connect(function()
Text:TweenSize(UDim2.new(hlth/mxhlth,0, 1,0), "Out", "Linear", .2, true)
end)

end)

also can someone tell me why regeneration script wont work? i have made a script to see if its disabled when the player enters but no still no work

i am talking about the "health" script when the player character is ingame``
