why image thumbnail start at the top instead of the bottom?

hi there, I am having a problem with this script. I had implemented the code and it works great to show the thumbnail. problem is that the thumbnail image somehow starts at the top and get down when the player height increases.

is there any way to change it to start at the bottom and work it way up when players' height increases?

here is the script for the leaderstats that records players height

local function OnPlayerJoin(player)
	
	 repeat wait() until player.Character
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	local Height = Instance.new("IntValue")
	Height.Name = "Height"
	Height.Parent = leaderstats
	while wait() do Height.Value = (player.Character.HumanoidRootPart.Position.Y - 8) end
end

game.Players.PlayerAdded:Connect(OnPlayerJoin)

here is the script for the thumbnail that will go up and down based on the leaderstat height

local MaxHeight = 200
local Player = game.Players.LocalPlayer
local LeaderStats = Player:WaitForChild("leaderstats")
local Height = LeaderStats:WaitForChild("Height")


local Icon = Instance.new("ImageLabel")
local START_POSITION = UDim2.new(0, 0, 0, 0)
Icon.BackgroundTransparency = 1
Icon.Size = UDim2.new(0.05,0,0.05,0)
Icon.Position = START_POSITION

local RatioConstraint = Instance.new("UIAspectRatioConstraint",Icon)

local UserId = Player.UserId
local ThumbnailType = Enum.ThumbnailType.HeadShot
local ThumbnailSize = Enum.ThumbnailSize.Size420x420
local Thumbnail, isReady = game.Players:GetUserThumbnailAsync(UserId, ThumbnailType, ThumbnailSize)
Icon.Image = Thumbnail
Icon.Parent = script.Parent

local function PlaceIcon()
    Icon:TweenPosition(UDim2.new(0.95,0,(Height.Value/MaxHeight),0),Enum.EasingDirection.In,Enum.EasingStyle.Sine,0.2,true)
end

game:GetService("RunService"):BindToRenderStep("BindPosition", 1, PlaceIcon)

I am wondering what's wrong with the code above that makes the image thumbnail start at the top instead of the bottom.

It's because the starting Y value was 0 so it was placed at the top So if you noticed, I made the starting Y value 0.95

	local MaxHeight = 200
	local Player = game.Players.LocalPlayer
	local LeaderStats = Player:WaitForChild("leaderstats")
	local Height = LeaderStats:WaitForChild("Height")
	  
	local Icon = Instance.new("ImageLabel")
	local START_POSITION = UDim2.new(0, 0, 0.95, 0)
	Icon.BackgroundTransparency = 1
	Icon.Size = UDim2.new(0.05,0,0.05,0)
	Icon.Position = START_POSITION
	 
	local RatioConstraint = Instance.new("UIAspectRatioConstraint",Icon)
	 
	local UserId = Player.UserId
	local ThumbnailType = Enum.ThumbnailType.HeadShot
	local ThumbnailSize = Enum.ThumbnailSize.Size420x420
	local Thumbnail, isReady = game.Players:GetUserThumbnailAsync(UserId, ThumbnailType, ThumbnailSize)
	Icon.Image = Thumbnail
	Icon.Parent = script.Parent
	 
	local function PlaceIcon()
	    Icon:TweenPosition(UDim2.new(0.95,0,(Height.Value/MaxHeight),0),Enum.EasingDirection.In,Enum.EasingStyle.Sine,0.2,true)
	end
	 
	game:GetService("RunService"):BindToRenderStep("BindPosition", 1, PlaceIcon)
