Code refuses to change the text of a label? (No Errors)

--> Functions
ChangeTitle = function(newTitle)
	for i,v in pairs(game.Players:GetChildren()) do
		local toChange = v.PlayerGui:WaitForChild("GameGUI").Title
		toChange.Text = newTitle
	end
end
--> Main Game Code
if #CurrentPlayers >= 2 then
	print("More.")
	ChangeTitle("Round starting in 30 seconds!")
elseif #CurrentPlayers < 2 then
	print("Less.")
	ChangeTitle("Waiting for more players!")
end

Before this, I had an event in Rep where I would call upon from a ServerScript. It was defined in a local-script to take the parameter given upon being called by the ServerScript and to use that to replace the text of the TextLabel.

I'm not understanding what i'm doing wrong here, it seems so simple. But, I have no errors in the console..?

It just won't change the text of the TextLabel.

First of all, are you using a local script?

Secondly, if I am not mistaken, to get the players of the Service players, you can just use :GetPlayers() instead of children.

--> Functions
ChangeTitle = function(newTitle)
    for i,v in pairs(game.Players:GetPlayers()) do
        local toChange = v.PlayerGui:WaitForChild("GameGUI").Title
        toChange.Text = newTitle
    end
end
--> Main Game Code
if #CurrentPlayers >= 2 then
    print("More.")
    ChangeTitle("Round starting in 30 seconds!")
elseif #CurrentPlayers < 2 then
    print("Less.")
    ChangeTitle("Waiting for more players!")
end

Also, make sure you are looking at output for errors.
