Looping an onRollOver...big deal...HELP!

Hi yall!!
Ok I got a problem that may seem simple for u guys but it’s giving me headaches…
I got four buttons on my clip : one says up, one says down, one says left, one says right.
Whenever the mouse pointer rollsover one of these, the image moves untill the mouse pointer rolls out.

here’s the code

On frame one :

up.onRollOver = function () {
_parent.pages._y = _parent.pages._y-10;
}
down.onRollOver = function () {
_parent.pages._y = _parent.pages._y+10;
}
left.onRollOver = function () {
_parent.pages._x = _parent.pages._x-10;
}
right.onRollOver = function () {
_parent.pages._x = _parent.pages._x+10;
}

On frame two :

gotoAndPlay (1);

In theory this should work, but doesn’t. (_parent.images refers to the clip that is supposed to move :drool:)
Any ideas?
