well this value isent working at all help?????????

Firstly you shouldn't store a value of the amount of players in ReplicatedStorage, it's pointless.

Let's create the variables.

local label = game.StarterGui.ScreenGui.Frame.TextLabel

Now let's check if there is only one or less people in the lobby. If not, we'll update the label.

while game.Players.NumPlayers < 2 do
    label.Text = "You need 2 players to start a round"
    repeat wait() until game.Players.NumPlayers >= 2 -- Wait until the minimum amount of players have joined.
end

Full Code:

local label = game.StarterGui.ScreenGui.Frame.TextLabel

while game.Players.NumPlayers < 2 do
    label.Text = "You need 2 players to start a round"
    repeat wait() until game.Players.NumPlayers >= 2
end
