How do i connect my light script to my group script?

Ok, so I have two scripts one is for turning my light switch on and off the other is to set it so that only group members can use the light switch. The problem is im a bit confused on how to connect them so that it works and I'm a bit confused on what to do.

Light switch script

function LightSwitchwork()
	local state = script.Parent.Parent.Parent.LightState
	local switch = script.Parent
	local lamp = state.Parent.Light.Lamp
	local light = state.Parent.Light.Lamp.SurfaceLight
	local bulb1 = lamp.Parent.Bulbs.bulb1
	local bulb2 = lamp.Parent.Bulbs.bulb2
	local noise = script.Parent.Parent.SwitchBase.on
	local noiseoff = script.Parent.Parent.SwitchBase.off
	local lampnoise = script.Parent.Parent.Parent.Light.LampBase.noise
	if state.Value == false then
		lampnoise.Volume = 0
		noise:Play()
		lampnoise:Play()
		state.Value = true
		lamp.BrickColor = BrickColor.new("Pastel yellow")
		lamp.Transparency = 1
		light.Enabled = true
		bulb1.Material = "Neon"
		bulb2.Material = "Neon"
		switch.BrickColor = BrickColor.new("Black")
		switch.CFrame = switch.CFrame*CFrame.fromEulerAnglesXYZ(0,0,0.4)
	else
		lampnoise.Volume = 0
		lampnoise:Stop()
		noiseoff:Play()
		state.Value = false
		lamp.BrickColor = BrickColor.new("Medium stone grey")
		lamp.Transparency = 1
		light.Enabled = false
		bulb1.Material = "SmoothPlastic"
		bulb2.Material = "SmoothPlastic"
		switch.BrickColor = BrickColor.new("Really black")
		switch.CFrame = switch.CFrame*CFrame.fromEulerAnglesXYZ(0,0,-0.4)
	end
	wait(1.5)
	lampnoise.Volume = 0
end
script.Parent.ClickDetector.MouseClick:connect(LightSwitchwork)

group script

local groupId = 380900
local minRank = 254
local lamp = script.Parent.Parent.Lamp

script.Parent.ClickDetector.MouseClick:Connect(function(plr)
    if plr:GetRankInGroup(groupId) >= minRank then 
        
    end
end)

after the "then" i got really confused. If i could get some help i would really appreciate it. I tried reading the article that went along for group ranks but i feel like i didnt help.
