Actionscripting (2 and/or 3) a walk...

[ArtisticSkytzo]

I had a huge greeting typed out, but now it's gone. In a nutshell, I'm here because I happen to think the people of this forum are quite intelligent.

I am currently programming a game, a flash game. I've managed to get the scripting right for a concept sprite to move and jump, but the walk animation doesn't... animate. I'm guessing the actionscripting inside the sprite's movieclip isn't assigned to the right frames, or the wrong actions are being commanded. What I need are the proper actions and frame assignments for the sprite's movieclip.
What I'm using:
Flash CS5
Actionscript 2 and 3 (I'll take advice for both, or either)
Mac OS

Feel free to ask for more details.

Any help would be tremendously (yes, that much) appreciated. Apologies if this or a topic like this has been posted, I made an effort to look.
