Some simple questions

Hi, I am fresh to Flash and have the following questions:

  1. I have a frame that display some text and I want it to hold for 30 seconds and then go to the next frame. Is it possible to use ActionScript to do that?

  2. I saw some Flash website which have a loading bar or counter. How to do that?

  3. My Flash file contain 7 scences, can each scene has an individual loading bar?

Thanks!
