Do i need .root or .parent?

Hi guys, I’m creating a course program and im a little stuck. I have 3 frame in a movie clip (not on the root menu) that contain movie clips. I have 2 buttons in the first frame that go to the other two frames depending on which is pressed. button 1 goes to frame 2 and then inside the movie clip to play an animation. Button two does exactly the same but plays a different animation inside the 3rd frame.

What i need is for the animation that gets played to return up a level to the first frame in the movie clip above and stop ready to be played again if the same button is pressed. What would be the best coding for this? I havnt got a clue of the syntax i need. Iv seen people using .root and .parent but i dont no which i would use?

please help me if you can.

Really appreciate it!
