Click Detector Not Working Because of Filtering Enabled, How would you fix it?

This script is suppose to move this entire model, by only clicking on one part. However, it isn't working properly....

No output errors, Ive tried same script in local and regular.

The script has to work with Filtering Enabled

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 

function onClicked() 
    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.OnClientEvent:connect(onClicked) 

If this is set up in a regular onclicked script it works, So im very confused.

I have tested this with and without filtering enabled activated. Doesn't work either way.
