SurfaceGui Only accessible to a specific group rank and above?

I am struggling with a issue at the moment. I have a GUI on a part and I am trying to make it so only the frame that allows you to control it is visible to people above a certain rank. It is supposed to change from the "Disabled" gui to "ShutterController" gui but it isn't working. May somebody be able to help me solve this issue I am having. The code is below. Just so you know the lowestViewRank will be set higher and I am in the group and above that rank number but the GUI is not changing.

local groupId = 5002973
local groupService = game:GetService("GroupService")
local lowestViewRank = 1
local HighestViewRank = 255

if game.Players.LocalPlayer:GetRankInGroup(lowestViewRank) < HighestViewRank then
	script.Parent:FindFirstChild("Disabled").Visible = false
	script.Parent:FindFirstChild("ShutterController").Visible = true
end

lowestViewRank isn't the group you are checking, it's the rank.

The

GetRankInGroup()

Function requires the group id as the parameter, NOT the lowest rank. It returns that player's rank in that specific group.

So, you would do:

if game.Players.LocalPlayer:GetRankInGroup(groupId) >= lowestViewRank and game.Players.LocalPlayer:GetRankInGroup(groupId) <= HighestViewRank then
	
	script.Parent:WaitForChild("Disabled").Visible = false
	script.Parent:WaitForChild("ShutterController").Visible = true
	
 end

It has not seemed to have of worked the code is below so you can see if I wrote it correct, the Local Script is in the surfacegui and I dont know what is causing it to stop it from changing.

local groupId = 5002973
local groupService = game:GetService("GroupService")
local lowestViewRank = 1
local HighestViewRank = 255

if game.Players.LocalPlayer:GetRankInGroup(groupId) >= lowestViewRank and game.Players.LocalPlayer:GetRankInGroup(groupId) <= HighestViewRank then

    script.Parent:FindFirstChild("Disabled").Visible = false
    script.Parent:FindFirstChild("ShutterController").Visible = true

 end

Try this script: Also make sure this is in a local script inserted in startergui If that doesn't work use a remote event

game.Players.PlayerAdded:Connect(function(Player)
    if Player:GetRankInGroup(5002973) >= 1 and  Player:GetRankInGroup  <= 255 then
script.Parent:FindFirstChild("Disabled").Visible = false
    script.Parent:FindFirstChild("ShutterController").Visible = true
        print("Player is the owner of the group, 'LOL'!")


    else
        print("Player is NOT the owner of the group, 'LOL'!")
    end
end)
