how can i make a sound play after u click the button?

so i have this script here in a clickdetector, you click a button and a door opens! how can i make a sound play when the button is clicked?

open=true

script.Parent.MouseClick:connect(function()
	if open==true then
		open=false
		script.Parent.Parent.Parent.Door.Transparency=1
		script.Parent.Parent.Parent.Door.CanCollide=false
		script.Parent.Parent.BrickColor=script.ButtonC.Value
		
	else
		open=true
		script.Parent.Parent.Parent.Door.Transparency=0
		script.Parent.Parent.Parent.Door.CanCollide=true
		script.Parent.Parent.BrickColor=script.ButtonO.Value
	end
end)

Insert a 'sound' object inside of the part with the clickdetector and do

open=true
sound1 = script.Parent.Parent.Sound1 -- Reference the sound object
sound2 = script.Parent.Parent.Sound2 -- Reference the sound object

script.Parent.MouseClick:connect(function()
    if open==true then
        open=false
        script.Parent.Parent.Parent.Door.Transparency=1
        script.Parent.Parent.Parent.Door.CanCollide=false
        script.Parent.Parent.BrickColor=script.ButtonC.Value
	sound1:Play() -- The method :Play will play the sound
    else
        open=true
        script.Parent.Parent.Parent.Door.Transparency=0
        script.Parent.Parent.Parent.Door.CanCollide=true
        script.Parent.Parent.BrickColor=script.ButtonO.Value
	sound2:Play()
    end
end)

Make sure you put the soundid in the soundid property inside the sound object.

For these scripts, simply indicate the parent of the child and how you want it to function (except for the new instance part.) For example, game is always the first parent. What is inside of the game is Workspace, etc. What is inside of Workspace is... and so on. The child is what is inside of the parent (Workspace is the child of the game...)

You could create a new instance (Thing) like so:

Instance.new("Sound", game.InsertParentNameHere)

It is recommended to use the Workspace as the parent of the sound.

And since the sound needs an ID to work, add another line of script to give the sound the ID of choice. To find the ID of the sound you want to use, find it on the Roblox website and copy the numbers on the search bar.

game.InsertParentNameHere.SoundId = "InsertIDHere"

All you need to do after that is make the sound play. Under the line that connects the mouse click to the functions, you can type this:

game.InsertParentNameHere.Sound:Play()

You can also just make the sound without the script in the Studio and then use the :Play() function below the connection of mouse click and functions.
