My first flash platform game

I’m making my first platform game based on this tutorial: http://www.kirupa.com/developer/mx2004/platform_game.htm

My game: http://projects.vindicate.us/flashgame.html

I’ve run into a couple of problems.

First of all, the character is supposed to jump on up arrow, and it does move up (and stays there!), but obviously, I want it to jump like the ball in the tutorial.

Also, I would like the character to not be able to walk to the left (in the beginning).

And last, I want there to be a little “ding” playing when the character picks the strawberries. I have the wav file, I just don’t know what to do with it.

Yes, I am new to this.
