How do I stop a movie clip from looping

I am using Action Script 3 and the 'stop()' function is not working to stop my movie clips from looping continuously.

I have added the 'stop()' function to the last frame on the timeline of each movie clip.

I originally built the .fla file in Flash CS6 using Action Script 2 where it was working with no problems (I have since upgraded and don't have access to CS6 anymore).

I have all the separate movie clips positioned on Frame 1 of my main stage with the following script to start them playing:

Cigarette_Reveal.play();

KickTheHabit.play();

BallMove.play();

BallFlip.play();

Offer.play();

I want each of these movie clips to stop playing after one animation sequence is complete.

Please help!
