Transitions

Hi, I don’t know if this question has been answered before or not. My questions is this, I need help with transitions between one scene to another. I have a button that when you click on it to plays a little motion tween. and that part I can figure out. what I need help with is that I want to be able to click on another button and have another motion tween play before it goes to a different scene. I figure this should be fairly easy, I am just very new at action scripting. if it helps any the site I am working is http://www.Brystin.com if you click one of the buttons you will see the motion tween I was talking about. I want to have the words slide to the other side when a button is clicked.

Thanks for any help you can give me!
