making random movement on only X axis

[blah-de-blah]

well i've read the random movement tutorial but now i only want things to move randomly horizontelly; on the x axis. I'm pretty sure this is possible since most things are with flash :)
so would anyone know what AS would be used? i've treid the one here:

and deleting stuff that i think is not relevant. But i keep getting more and more erros each time i try to fix something...so anyone know what the AS would be? thx

Well, if you delete everything that has something to do with _y, you should be able to make it work. Basically, instead of the last 2 lines
this._x = this.x;
this._y = this.y;just put
this._x = this.x;
