Am I doing Something wrong?

p = game.Players.LocalPlayer
[p: GetRankInGroup((2595428) == 1)then
    p:Kick()
end]

game.StarterGui:SetCoreGuiEnabled("All", false)
p.Character.Humanoid.WalkSpeed = 0

As you know, i am trying to see why it doesn't work What I am trying to say is that, I want it to be like when you are in a group and if your in the group at the first rank then the game shutdowns on you. But you must be in the group at the first rank to stay in the game.
