Basic Animations (AS2)

I'm relatively new to ActionScript and it's my first coding language. I've been practicing with it and I'm trying to make some animations for a character I created. It has some basic movements so far such as jumping, walking and swinging the sword, but I can't get it to swing while jumping or walking. I was wondering if someone could sift through the lines bad code and help me. It would also be great if someone could give me some pointers for what I could do better, because I've just basically been using if and else statements. Thanks!
