Having an Issue Attempting to Group Rank Lock something.

[cerulean zinc]

local P = script.Parent.Parent.Parent.Parent.Parent.Name
local HLoc = workspace:FindFirstChild(P)

function onClick(mouse)
    local Hat= HLoc:findFirstChild("Face1")
    Hat.Color.BrickColor = BrickColor.new("Really red")
    Hat.Color1.BrickColor = BrickColor.new("Really red")
    Hat.Color2.BrickColor = BrickColor.new("Bright yellow")
end

script.Parent.MouseButton1Down:connect(onClick)

I've tried Getingrouprank but idk what's happening because there's never an error.

I wanna make it where it only changes color of the helmet if the person is the rank needed.

Idk what string to put to check if player is in the group. And if so to then allow helmet color change.
