[Solved]Health Bar X Size getting bigger then Screen?

Hello everyone,

i have a problem with my screen bar if the player life is getting higher(power value = maxhealth+powervalue) then my health bar is sizing to much (Screen Shot) maybe someone see the error or soluation ?

local Players = game:GetService("Players")
local player = Players.LocalPlayer or Players:GetPropertyChangedSignal("LocalPlayer"):wait()
local character = player.Character or player.CharacterAdded:wait()

local PlayerLevel = player:WaitForChild("leaderstats").Level.Value
local human = character:FindFirstChild("Humanoid")
local health = human.Health
local maxhealth = human.MaxHealth
local PlayerXP = player:WaitForChild("playerdata"):WaitForChild("XP")

local xpToLevelUp = function(level)
	return 100 + level * 5
end

while wait() do
	local pourcentage = math.floor(player:WaitForChild("playerdata"):WaitForChild("XP").Value/xpToLevelUp(player:WaitForChild("leaderstats"):WaitForChild("Level").Value) * 100)
	if health then
		script.Parent:TweenSize(UDim2.new(player:WaitForChild("playerdata"):WaitForChild("XP").Value/xpToLevelUp(player:WaitForChild("leaderstats"):WaitForChild("Level").Value), 0, 1, 0))
		script.Parent.Parent.TextLabel.Text = pourcentage.. "%"
	end
end

#Screenshot

i already tryed something like that

	if health == maxhealth or health > maxhealth then
		script.Parent.Size = UDim2.new(1, 0,1, 0)
	end
