How would get a players' location from a global script?

I am trying to get the players' location using a global script, this is what I have written:

local location = Vector3.new(0,0.5,0)
local playerName = script.Parent.Parent.Parent.Parent.Name
local playerLocation = game.Workspace.playerName.UpperTorso.Position

print(playerLocation)

I don't know why but it keeps saying that playerName is an invalid member of Workspace. Should I put a wait so that ROBLOX has time to load the character? What do I do? Thank you/

You can use the PlayerAdded event and then wait for the player's character like so:

game:GetService("Players").PlayerAdded:Connect(function(player)
	local character = player.CharacterAdded:wait()
	local position = character:WaitForChild("HumanoidRootPart").Position
end)

If this answers your question, please accept this as the best answer!

Put the Global Script in Workspace. Then try this code:

game.Player.PlayerAdded:Connect(function(Plr) -- Player is added
Plr.CharacterAdded:Connect(function(Char) -- Players' character added

local location = Char:WaitForChild("UpperTorso").Position -- wait for uppertorso to appear then get the position

end)
end)

Change the code to

local location = Vector3.new(0,0.5,0)
repeat wait()

until script.Parent.Parent.Parent.Parent.Character
local playerName = script.Parent.Parent.Parent.Parent.Name
repeat wait()

until game.Workspace.playerName.UpperTorso
local playerLocation = game.Workspace.playerName.UpperTorso.Position

print(playerLocation)
