Guiscreen not working when character hits a model?

script.Parent.Touched:Connect(function(hit)
	if hit.Parent.FindFirstChild("Humanoid")
	then
		game.ReplicatedStorage.FoundStar:FireClient(game.Players:GetPlayerFromCharacter(hit.Parent))
	end
end)

I want to make it when it hits the model(a star) it pops up with a Guiscreen telling them they have found the star. My code so far for the guiscreen is:

game.ReplicatedStorage.FoundStar.OnClientEvent:Connect(function()
    game.Players.LocalPlayer.PlayerGui.StarScreen.Enabled = true
end)

I don't know what the problem is ;/
