how do you make your own parent to child relationship?

im trying to make things more organize by making sound something like a property of the animationTrack even if it isnt

i will need sound to be a child of animationTrack to do that

i already got the animationTrack done and i have a script that automatically loads all the tracks in and put every single track into a table

now im just working on a prototype to find a way to make sound a child of animation

this is what i came up with for prototype which didnt work because either it printed out nil and animation or the table itself(table: 0x4c0c11c7bc45873e) and sound

local Table = {


    Animation = "Animation" and {
        Sound = "Sound"
                }

}

print(Table.Animation)
print(Table.Animation.Sound)

i dont really know what im doing wrong here

i want to achieve something similar to down below where i can reference Sound like a property

AnimationTrack.Animation.Sound
AnimationTrack.Animation
