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:

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

local SP			= script.Parent;

local GroupId		= Settings.GroupId;
local StaffRank		= Settings.StaffRank;
