How do I fix this team change button script in my team change GUI??

I wrote this script inside a text button which is inside a GUI, but it does not work. It is supposed to change their team when they click it, then respawn them so they spawn on that team.

local plr = game.Players.LocalPlayer
script.Parent.MouseButton1Click:Connect(function()
    plr.TeamColor = BrickColor.new("Rust")
    wait(1)
    plr.Character.Humanoid.Health = 0
end)
