SprintingAnimation:19: Expected ')' (to close '(' at column 29), got ',' - lua

Question

In my game I've made a feature where you can sprint.
I've separated the animation part of the script from the main sprinting part.
I got the error message "Workspace.Vlo_tz.SprintingAnimation:19: Expected ')' (to close '(' at column 29), got ','".
This code is for the animation of the character and the sprinting bar
local UIS = game:GetService('UserInputService')
local Player = game.Players.LocalPlayer
local Character = Player.Character
local players = game:GetService("Players")
local stamina = players.LocalPlayer.PlayerGui.StaminaHealth.MainFrame.Stamina
UIS.InputBegan:connect(function(input)
local humanoid = Player.Character.Humanoid
if input.KeyCode == Enum.KeyCode.LeftShift and humanoid:GetState() == Enum.HumanoidStateType.RunningNoPhysics and humanoid.MoveDirection.Magnitude > 0 then
local Anim = Instance.new('Animation')
Anim.AnimationId = 'rbxassetid://05168161960'
PlayAnim = Character.Humanoid:LoadAnimation(Anim)
PlayAnim:Play()
while true do
wait(0.05)
if stamina.Position <= (-0.343, 0, 0.274, 0) then
stamina.Position = UDim2.new(-0.343, 0, 0, 0)
else
stamina.Position = stamina.Position - UDim2.new(0.01, 0, 0, 0)
end
end
end
end)
UIS.InputEnded:connect(function(input)
if input.KeyCode == Enum.KeyCode.LeftShift then
PlayAnim:Stop()
while true do
wait(0.005)
if stamina.Position >= (0.487, 0, 0.274, 0) then
stamina.Position = UDim2.new(0.487, 0, 0, 0)
else
stamina.Position = stamina.Position + UDim2.new(0.01, 0, 0, 0)
end
end
end
end)
local humanoid = Player.Character.Humanoid
if humanoid.MoveDirection.Magnitude == 0 then
PlayAnim:Stop()
while true do
wait(0.005)
if stamina.Position >= (0.487, 0, 0.274, 0) then
stamina.Position = UDim2.new(0.487, 0, 0, 0)
else
stamina.Position = stamina.Position + UDim2.new(0.01, 0, 0, 0)
end
end
end

Line 19 is this : if stamina.Position <= (-0.343, 0, 0.274, 0) then
You have this check in a few different places, but this is not valid lua and you cannot compare UDim2 values like this. You'll have to inspect the values individually.
local isLessThanX = stamina.Position.X.Scale <= -0.343
local isLessThanY = stamina.Position.Y.Scale <= 0.274
if isLessThanX and isLessThanY then
