What you need to learn.

What do you do?
You need to make two buttons. The first one to play the movie, and the second one to send you back to frame one. You first make the buttons, then you will make them into a symbol, and then button. You double click on the symbol. You modify it by making it change colors so that people know that they are interacting with it. Go to Window, Actions, and make sure that Script Assist is turned on. Go to the plus sign. Global Functions, then Timeline Control, and put in the action that button is going to do. If it does not work, then you have done something wrong. Make sure that the symbol is in fact a button. Also make sure that that button does what you want it to do. If the problem persists, then contact your teacher. They will know what to do.

What you need to remember?
You need to remember to put the play and send to actions on the buttons. You also need another layer to stop the movie at key points on the animation. If its not cool, you will lose your audience. Then you will be FIRED!!!
