Remote Event is not being triggered. Please help, what am I doing wrong?

EVERYTHING IN BOLD FROM HERE ON OUT IS WHERE EVERY SCRIPT IS LOCATED. ABOVE IT IS WHAT TYPE OF SCRIPT IT IS. Alright so, this is suppose to trigger the event and change the pointlights color that is inside parts that is also inside a model. The first script is the one i'm having issues with, its a local script trying to fire server and it won't allow the FireClient or FireAllClients to happen. This script is a local script. game.Workspace.ArenaLights.White

Power = script.Parent.Power
--Made By MillerrIAm
--Helpers Liliardio & WeArefSociety
--------------------------------------------------------------------
--Start Script
function change()
	game.ReplicatedStorage.LightingEvents.ArenaLightsEvent:FireServer("White")
end
script.Disabled = true

This is what is suppose to to call for the script above to work. #2 This is a script, not local or module. game.Workspace.TronsFolder[NewTron].Main[Script|ArenaLights]

Power = script.Parent.Power
ArenaLights = game.Workspace.ArenaLights
--Made By MillerrIAm
--Helpers Liliardio & WeArefSociety
--------------------------------------------------------------------
--Start Script
Power.Changed:Connect(function(Value)
	if Value then
		while Power.Value do
			ArenaLights.White.Disabled = false
			wait(0.1)
			ArenaLights.Blackout.Disabled = false 
			wait(0.1) --Just duplicate this and the line above.
		end
	end
end)

This script works perfectly fine but I figured it could help.#3 This is a script, not a local script or a module script. game.ServerScriptStorage[Scripts|LightingEvents].[Script|ArenaLighting]

Lighting = game:GetService('Lighting') -- This line isn't needed though.
ReplicatedStorage = game.ReplicatedStorage
parts = game.Workspace.ArenaLights:GetChildren() 
--------------------------------
game.ReplicatedStorage.LightingEvents.ArenaLightsEvent.OnServerEvent:Connect(function(player,arenalight)
    local children = game.Workspace.ArenaLights:GetChildren()
    if arenalight == "BrightWhite" then --White Lighting
      for i, v in pairs(children) do
        if v:FindFirstChild("PointLight") ~= nil then
          v.PointLight.Color = Color3.fromRGB(255, 255, 255)
        end
      end
      wait(0.01)
    elseif arenalight == "White" then
      for i, v in pairs(children) do
        if v:FindFirstChild("PointLight") ~= nil then
          v.PointLight.Color = Color3.fromRGB(255, 255, 255)
        end
      end
      wait(0.01)
    elseif arenalight == "Blackout" then
      for i, v in pairs(children) do
        if v:FindFirstChild("PointLight") ~= nil then
          v.PointLight.Color = Color3.fromRGB(0, 0, 0)
        end
      end
      wait(0.01)
    end
end)

Thank you in advance for any help, comments & answers!

Try deleting the function in the first script, that should do the trick.

I believe the issue might be that your Change() Function is never being fired. You have set the Function but not called it. Try doing this:

Power = script.Parent.Power
--Made By MillerrIAm
--Helpers Liliardio & WeArefSociety
--------------------------------------------------------------------
--Start Script
function change()
    game.ReplicatedStorage.LightingEvents.ArenaLightsEvent:FireServer("White")
end

change()
script.Disabled = true

or

Power = script.Parent.Power
--Made By MillerrIAm
--Helpers Liliardio & WeArefSociety
--------------------------------------------------------------------
--Start Script
game.ReplicatedStorage.LightingEvents.ArenaLightsEvent:FireServer("White")

script.Disabled = true

Other then that, I can't find anything else wrong. Hope this fixes the problem. Best of Luck!
