How do I start with creating a Rank lock?

I've run into a problem where I'm trying to create a rank lock. I do not want them accessing all the morphs only the designated ones I've designed for them. The problem is, that nowhere online does it show this question. There was a similar question but didn't give much detail. I've tried to use this local script. But no such luck. Help a brother out.

local Allowed = true

                if v3:FindFirstChild("Rank") then
                    if Player:GetRankInGroup(Divisions[i].GroupId) >= v3:FindFirstChild("Rank").Value then
                        Allowed = true
                    else
                        Allowed = false
                    end
                end
              if Allowed then
                local Button2 = Instance.new("TextButton")
                Button2.Size = UDim2.new(1,0,0,50)
                Button2.BackgroundTransparency = 1
                Button2.Font = "SourceSans"
                Button2.TextSize = 30
                Button2.TextXAlignment = "Left"
                Button2.TextColor3 = Color3.fromRGB(255,255,255)



                Button2.Text = v3.Name
                Button2.Parent = UniformsFrame

                Button2.MouseButton1Click:connect(function ()


                    RemoveObjects()

                    if v3:FindFirstChild("Leg1") then
                        GiveHelmet(v3.Leg1, "Left Leg")
                    end
                    if v3:FindFirstChild("Leg2") then
                        GiveHelmet(v3.Leg2, "Right Leg")
                    end
                    if v3:FindFirstChild("Arm1") then
                        GiveHelmet(v3.Arm1, "Left Arm")
                    end
                    if v3:FindFirstChild("Arm2") then
                        GiveHelmet(v3.Arm2, "Right Arm")
                    end
                    if v3:FindFirstChild("Chest") then
                        GiveHelmet(v3.Chest, "Torso")
                    end
                    if v3:FindFirstChild("Helmet") then
                        GiveHelmet(v3.Helmet, "Head")
                    end
                    SelectedMorph = v3

                    script.Parent.Parent.Spawn.Visible = true
                end)
            end
            end
        end)
    end
end
