Intro to ActionScript

This designing a game is really hard for an adult for several reasons: 1) I'm always afraid that I will do something wrong or ruin what I have already done. I am still not comfortable with this technology but definitely want to learn how to use it effectively and 2) my worst fear is that I will fall "flat on my face" due to my lack of early exposure to programming language and unfamiliarity with utilizing the assets necessary even inside of the wiki format.
