gui stretching away from eachother when using diffrent screen size. How to fix?

So I have made a script that makes a GUI that can teleport a player to another. But when someone has a different screen size than me. The GUI button and guitextbutton move from each other. Can anyone fix?

local loc = game.Players.LocalPlayer.PlayerGui
local screengui = Instance.new("ScreenGui", game.StarterGui)
local frame = Instance.new("Frame", game.StarterGui.ScreenGui)
local textbox1  = Instance.new("TextBox", game.StarterGui.ScreenGui.Frame)
local textbox2 = Instance.new("TextBox", game.StarterGui.ScreenGui.Frame)
local textbutton = Instance.new("TextButton", game.StarterGui.ScreenGui.Frame)
frame.Size = UDim2.new(0, 252,0, 121)
textbox1.Size = UDim2.new(0, 252,0, 94)
textbox2.Size = UDim2.new(0, 252,0, 94)
textbutton.Size = UDim2.new(0, 252,0, 70)
screengui.Parent = loc
frame.Parent = loc.ScreenGui
textbox1.Parent = loc.ScreenGui
textbox2.Parent = loc.ScreenGui
textbutton.Parent = loc.ScreenGui
textbox2.Position = UDim2.new(0, 0,0.124, 0)
textbutton.Position = UDim2.new(0, 0,0.248, 0)
frame.BackgroundColor3 = Color3.new(255, 255, 255)
textbox1.BackgroundColor3 = Color3.new(255, 255, 255)
textbox2.BackgroundColor3 = Color3.new(255, 255, 255)
textbutton.BackgroundColor3 = Color3.new(255, 255, 255)
textbox1.Text = ("Player1")
textbox2.Text = ("Player2")



textbutton.MouseButton1Click:Connect(function(tel)
local txtboxtext = textbox2.Text
local player = textbox1.Text
local playerhun = game.Workspace:FindFirstChild(player)
local player2 = game.Workspace:FindFirstChild(txtboxtext)
local player2pos = player2.HumanoidRootPart.Position
print(player2pos)
playerhun:MoveTo(player2pos)
end)
