How to make a Flash game using Actionscript?

I am making a platform game using flash and I am having a little trouble, so I would like to know how to make a running character by pressing an arrow key down. I鈥檝e already set up the characters key frame in flash in an animation to run, what I am trying to do is make it run when an arrow key is press down and stops running when a arrow key isn鈥檛 being pressed, actionscript is tricky.How to make a Flash game using Actionscript?
There is a MC with 4 frame inside.


1st frame: front (frame name: front) (MC name: MCfront)


2nd frame: back (frame name: back) (MC name: MCback)


3rd frame: left (frame name: left) (MC name: MCleft)


4th frame: right (frame name: right) (MC name: MCright)





Each of these frames has another MC that has 2 more frames inside.


1st frame: still image


2nd frame: walking animation





Remember to put ';stop();'; on all of these frames.


The following AS is to be put on the first MC:





onClipEvent(enterFrame){


if(Key.isDown(Key.RIGHT)){


this._x += 4.5;


this.gotoAndStop(';right';);


this.MCright.gotoAndStop(2);


}else{


this.MCright.gotoAndStop(1);


}


if(Key.isDown(Key.LEFT)){


this._x -= 4.5;


this.gotoAndStop(';left';);


this.MCleft.gotoAndStop(2);


}else{


this. MCleft.gotoAndStop(1);


}


if(Key.isDown(Key.UP)){


this._y -= 4.5;


this.gotoAndStop(';back';);


this.MCback.gotoAndStop(2);


}else{


this. MCback.gotoAndStop(1);


}


if(Key.isDown(Key.DOWN)){


this._y += 4.5;


this.gotoAndStop(';front';);


this.MCfront.gotoAndStop(2);


}else{


this. MCfront.gotoAndStop(1);


}


}
