Is there a way to display this on a TextLabel for everyone? [Unanswered]

I have a TextLabel, and i want it's text to be the the player that is the highest in the server, with their torsos y position. I wasn't so sure how to go about doing this, but this is all I got:

repeat wait() until game.Players.LocalPlayer

plr= game.Players:GetPlayers()
value = plr.LocalPlayer.PlayerGui.Value.Value

for i = 1,#plr do
    if value > plr[i].PlayerGui.Value.Value then
        while wait(1) do
            script.Parent.Text = plr[i].Name.. ": ".. value
        end
    end
end

I'm stumped and I need help.

This is the error I'm getting
