How to activate a script by using onTouched()?

This is the script I have come up with, I want to activate "sound", which "is already in the same part as this script. I am getting warned "Unknown Global Sound". I apologize if this may seem stupid, brand new to this stuff.

function onTouched()
	local script = Sound
	Sound.Disabled = false
end

script.Parent.Touched:Connect (onTouched)

• There was some typing errors.

 function onTouched()
    local Sound= script.Sound; -- If the script is inside the this script parent
    Sound.Disabled = false;
end
 
script.Parent.Touched:Connect(onTouched);
