Why won't my group rank GUI work?

The idea is to only move the GUI if the player is a certain rank or higher in a group. Except that doesn't happen. Can anyone help?

player = game.Players.LocalPlayer

if player:GetRankInGroup(2796272) >= 253  then 
	script.Parent.Parent = player.PlayerGui

end

Are you sure your group ID is correct? If so, then maybe try making the parenthesis right next to the numbers instead of having a space at the start and end.
