Why isn't my module script working? I can't understand that.. Is that my or roblox fault?

So, just I wanted to make a Blackout script with Emergency Power and when I click at the button which calls the function It wont work but if I execute the same command in Studio Command Bar then it works normally.

Button:

local b = require(game.ServerScriptService.Blackout)
script.Parent.ClickDetector.MouseClick:Connect(function()
    b.EmPower("All")
end

Module Script:

    local Blackout = {}

local bulb = 120,150,0

local light = 120,150,0

local normal = 253,253,253



local CDC = workspace.CDC.Lights

local LCZ = workspace.LCZ.Lights

local MCZ = workspace.MCZ.Lights

local HCZ = workspace.HCZ.Lights

local EZ = workspace.EZ.Lights

Blackout.StatusLCZ = false

Blackout.StatusMCZ = false

Blackout.StatusHCZ = false

Sorry for formating lol it broke.. I just really don't know where is the mistake or something.. (Button Script is ServerScript)
