HELP! Animating using actionscript

Hi All,

I’m having a bit of trouble with some actionscript.

I have a movie with an instance name of myBook. myBook has these actions on it.

onClipEvent(load){
_root.myBook._x = 152;
_root.myBook._y = 323;
_root.targXscale=100;
_root.targYscale=100;
}

I have a button that tells the movie clip (myBook) to move a certain distance to the right. This in the action on the button.

on (rollOver) {
_root.myBook._x = 870;
_root.myBook._y = 323;
gotoAndStop(10);

}

So far so good…but this is when I get stuck.

You see, the button makes the movie clip (myBook) jump to its new position. I want it to motion tween (animate) to its new position…NOT…jump suddenly to it.

I would appreciate some help please.
