Script for Overhead GUI not working, I don't understand why. What do I have to fix?

Hello, please help me fix this script. I don't understand why it doesn't work. The output gives no information.

local group1 = 15108164; -- GroupId
local group2 = 2; -- Same here
local group3 = 3; -- Ok bye
local group4 = 4;
local group5 = 5;
local group6 = 6;
local redacted = 666;
local vipgroup = 15108164;
local x = nil -- change nil to RankID for VIP tag. Add "and (GetRankInGroup(player, group1))) >= x" if you want that only specific rank above x can be VIP at line 34

local VipRank = script:WaitForChild("VipRank");
local RankTagging = script:WaitForChild("RankTag");
local RedactedTag = script:WaitForChild("Redacted");

function GetRankInGroup(RedactedTag, i)
    return RedactedTag:GetRankInGroup(i)
end

function GetRoleInGroup(RedactedTag, i)
    return RedactedTag:GetRoleInGroup(i);
end

function IsInGroup(RedactedTag, i)
    return RedactedTag:IsInGroup(i)
