Can somebody tell me how do I make a textlabel show the team the player is currently on?

I've been trying for a few hours to do this,but it just wouldn't work.

--Just put the Gui in the corrisponding team.

function teamFromColor(color)

for _,t in pairs(game:GetService("Teams"):GetChildren()) do

if t.TeamColor==color then return t end

end

return nil

end

function onSpawned(plr)

local gui = teamFromColor(plr.TeamColor):GetChildren()

for _,c in pairs(gui) do

c:Clone().Parent = plr.PlayerGui

end

end

function onChanged(prop,plr)

if prop=="Character" then

onSpawned(plr)

end

end

function onAdded(plr)

plr.Changed:connect(function(prop)

onChanged(prop,plr)

end)

end

game.Players.PlayerAdded:connect(onAdded)
