Why is this group rank only tool script not working? - Thanks :)

Like the title says, the script is meant to give them certain tools on the game but for some reason it isn't working. Any help is appreciated thanks.

local Folder = game.ServerStorage.ToolStorage
local Debit = Folder["Debit Card "]
local Access = Folder["Access Card"]
local Fire = Folder["Armodia FireKey"]
local Search = Folder["EAS Search Tool"]
local Cuffs = Folder["HandCuffs"]
local TestTag = Folder["JSM Test Tag"]
local SelfServ = Folder["JSM Self-Serv Key "]
local Phone = Folder["Phone"]
local Barcode = Folder["[JSM] Operator Barcode"]

Any help is appreciated. Also the group id is 13874159 and the Game iD is 9101331434 if that helps - thanks.

Also, game.ServerStorage.ToolStorage does exist and we put all the tools in there :)
