Is It Possible...

Is it possible to make a movieclip that has been loaded in using the .attachMovie function move around the stage with the following code?


Code:
onClipEvent (load){
xspeed = random (17) + 18;
yspeed = random (17) + 18;
}

onClipEvent (enterFrame){
this._x +=xspeed;
this._y +=yspeed;
}
Ive tried everything i can think of but none of my attempts have worked. Any help would be much appreciated

Thanks in Advance
