Filtering Enabled Click Detector, Any Help? [Edited}"

This script is suppose to only activate upon one part being clicked. I have filtering Enabled on and I am confused why it isn't working properly. This is set up inside a model. So that when a certain part is clicked then the rest of the model moves.

Classes

Model = 2Children[Main]&[Model]

Main is the part being clicked and the other model ha all the other parts inside of it. Which makes it so only one single part can be clicked. Inside a model.

Here is the script:

wait(1)
script.Parent.PrimaryPart = script.Parent.Main
local Main = script.Parent:GetPrimaryPartCFrame()
local part = script.Parent.Main
local clic = part.ClickDetector
local sound = script.Parent.Sound
local Sensor = part -- Path to the Click Sensor can change

function onClicked() -- Add whatever you want the button to do into the function
	if script.Parent.Open.Value == 1 then 
	sound:Play()
	fix = script.Parent.Main.CFrame 
	for i = 0,1.5,0.1 do
		wait(0.05)
		script.Parent:SetPrimaryPartCFrame(script.Parent.Main.CFrame*CFrame.fromEulerAnglesXYZ(0,-0.1,0)*CFrame.new(0.01,0,-0.25))
		script.Parent.Open.Value = 0
		clic.MaxActivationDistance = 0
	end
		script.Parent:SetPrimaryPartCFrame(fix*CFrame.fromEulerAnglesXYZ(0,-math.pi/2,0)*CFrame.new(-2.5,0,-2.5))
		wait(0.25)
		clic.MaxActivationDistance = 15
	elseif script.Parent.Open.Value == 0 then
		sound:Play()
		fix = script.Parent.Main.CFrame 
	for i = 0,1.5,0.1 do
		wait(0.05)
		script.Parent:SetPrimaryPartCFrame(script.Parent.Main.CFrame*CFrame.fromEulerAnglesXYZ(0,0.1,0)*CFrame.new(-0.01,0,0.25))
		clic.MaxActivationDistance = 0
	end
		script.Parent:SetPrimaryPartCFrame(fix*CFrame.fromEulerAnglesXYZ(0,math.pi/2,0)*CFrame.new(-2.5,0,2.5))
		wait(0.25)
		clic.MaxActivationDistance = 15
		script.Parent.Open.Value = 1
	end
end

part.ClickEvent.OnServerEvent:connect(onClicked) -- Make sure ClickEvent and ClickDetector are inside the ClickSensor
