How can i update my health bar ui when the max health changes?

Just as the title says, so im using a radial health bar ui that works perfectly fine until i change the max health. When the max health changes the ui dosent update it says the same.

Heres the code:

local Humanoid = game.Players.LocalPlayer.Character:WaitForChild("Humanoid")

game:GetService("RunService").RenderStepped:Connect(function()
    script.Parent.Value = Humanoid.Health
    -- Progress.
    local PercentNumber = math.clamp(script.Parent.Value * 3.6,0,360)
    local F1 = script.Parent.Parent.Frame1.ImageLabel
    local F2 = script.Parent.Parent.Frame2.ImageLabel
    F1.UIGradient.Rotation = script.FlipProgress.Value == false and math.clamp(PercentNumber,180,360) or 180 - math.clamp(PercentNumber,0,180)
    F2.UIGradient.Rotation = script.FlipProgress.Value == false and math.clamp(PercentNumber,0,180) or 180 - math.clamp(PercentNumber,180,360)
    F1.ImageColor3 = script.ImageColor.Value
    F2.ImageColor3 = script.ImageColor.Value
    F1.ImageTransparency = script.ImageTrans.Value
    F2.ImageTransparency = script.ImageTrans.Value
    F1.Image = "rbxassetid://" .. script.ImageId.Value
    F2.Image = "rbxassetid://" .. script.ImageId.Value
    if script.MissingPartType.Value == "Color" then
        F1.UIGradient.Color = ColorSequence.new({ColorSequenceKeypoint.new(0,script.ColorOfPercentPart.Value),ColorSequenceKeypoint.new(0.5,script.ColorOfPercentPart.Value),ColorSequenceKeypoint.new(0.501,script.ColorOfMissingPart.Value),ColorSequenceKeypoint.new(1,script.ColorOfMissingPart.Value)})
        F2.UIGradient.Color = ColorSequence.new({ColorSequenceKeypoint.new(0,script.ColorOfPercentPart.Value),ColorSequenceKeypoint.new(0.5,script.ColorOfPercentPart.Value),ColorSequenceKeypoint.new(0.501,script.ColorOfMissingPart.Value),ColorSequenceKeypoint.new(1,script.ColorOfMissingPart.Value)})
        F1.UIGradient.Transparency = NumberSequence.new(0)
        F2.UIGradient.Transparency = NumberSequence.new(0)
    elseif script.MissingPartType.Value == "Trans" then
        F1.UIGradient.Transparency = NumberSequence.new({NumberSequenceKeypoint.new(0,script.TransOfPercentPart.Value),NumberSequenceKeypoint.new(0.5,script.TransOfPercentPart.Value),NumberSequenceKeypoint.new(0.501,script.TransOfMissingPart.Value),NumberSequenceKeypoint.new(1,script.TransOfMissingPart.Value)})
        F2.UIGradient.Transparency = NumberSequence.new({NumberSequenceKeypoint.new(0,script.TransOfPercentPart.Value),NumberSequenceKeypoint.new(0.5,script.TransOfPercentPart.Value),NumberSequenceKeypoint.new(0.501,script.TransOfMissingPart.Value),NumberSequenceKeypoint.new(1,script.TransOfMissingPart.Value)})
        F1.UIGradient.Color = ColorSequence.new(Color3.new(1,1,1))
        F2.UIGradient.Color = ColorSequence.new(Color3.new(1,1,1))
    elseif script.MissingPartType.Value == "TransAndColor" then
        F1.UIGradient.Transparency = NumberSequence.new({NumberSequenceKeypoint.new(0,script.TransOfPercentPart.Value),NumberSequenceKeypoint.new(0.5,script.TransOfPercentPart.Value),NumberSequenceKeypoint.new(0.501,script.TransOfMissingPart.Value),NumberSequenceKeypoint.new(1,script.TransOfMissingPart.Value)})
        F2.UIGradient.Transparency = NumberSequence.new({NumberSequenceKeypoint.new(0,script.TransOfPercentPart.Value),NumberSequenceKeypoint.new(0.5,script.TransOfPercentPart.Value),NumberSequenceKeypoint.new(0.501,script.TransOfMissingPart.Value),NumberSequenceKeypoint.new(1,script.TransOfMissingPart.Value)})
        F1.UIGradient.Color = ColorSequence.new({ColorSequenceKeypoint.new(0,script.ColorOfPercentPart.Value),ColorSequenceKeypoint.new(0.5,script.ColorOfPercentPart.Value),ColorSequenceKeypoint.new(0.501,script.ColorOfMissingPart.Value),ColorSequenceKeypoint.new(1,script.ColorOfMissingPart.Value)})
        F2.UIGradient.Color = ColorSequence.new({ColorSequenceKeypoint.new(0,script.ColorOfPercentPart.Value),ColorSequenceKeypoint.new(0.5,script.ColorOfPercentPart.Value),ColorSequenceKeypoint.new(0.501,script.ColorOfMissingPart.Value),ColorSequenceKeypoint.new(1,script.ColorOfMissingPart.Value)})
    else
        script.MissingPartType.Value = "TransAndColor"
    end
end)

how would i go about the ui updating when the max health changes?
