How To Fix My Door That Make Sound When Click?

I made a door that make sound when someone click on it. And I also added in a code that when someone say like "open up" the door will open, but it's not working. Can someone help me?

Here is my door and script layout so it's easier to know what I'm talking about:

And my script is down below:

Brick = script.Parent
Sound = Brick.Sound
Debounce = false

function onClicked()
    if not Debounce then -- If the debounce is false
        Debounce = true -- Change it to true
        Sound:Play()
        wait(Sound.TimeLength) -- Wait til it ends
        Debounce = false -- Change it to false
    end -- End the if function
end

script.Parent.ClickDetector.MouseClick:connect(onClicked)

door = script.Parent --this is the door 

function onChatted(msg, recipient, speaker) 

-- convert to all lower case 

local source = string.lower(speaker.Name) 
msg = string.lower(msg) 

if (msg == "open up") then 
door.CanCollide = false 
door.Transparency = 0.7 
wait(5) 
door.CanCollide = true 
door.Transparency = 0 
end 

end 

function onPlayerEntered(newPlayer) 
newPlayer.Chatted:connect(function(msg, recipient) onChatted(msg, recipient, newPlayer) end) 
end 

game.Players.ChildAdded:connect(onPlayerEntered)
