Why is this not Saving or Loading?

So, this script is supposed to Save and Load the time spent in-game by the people above or that rank in the group, but it prints this error after it has counted 1 minute, can anyone help me understand why it thinks it is missing or nil?

-- Argument 2 missing or nil

-- Script 'ServerScriptService.StaffTime.StaffTimeCounter', line 74 - global TimeCount

-- Script 'ServerScriptService.StaffTime.StaffTimeCounter', line 94

-- Stack end

The script is:

-- Primary Variables:
local DataStore     = game:GetService('DataStoreService'):GetDataStore('StaffTime');

local SP            = script.Parent;

local Default       = Users:WaitForChild('Default');

local Settings      = require(SP:WaitForChild('Settings'));
local GroupId       = Settings.GroupId;
