[CS3/F8]AS2 Stopping a tween from moving

Hi all, I have a yellow square that i am tweening along the x axis using the .tween class, however this animation starts as soon as the frame is loaded, i have tried several ways to make it start at a stationary position yet to no avail.
The play control works so far and it does loop the animation like i want it to yet i just want the square to start at a stop.
I also need a working stop button as i can only make it pause curently.
I have uploaded a working .zip file with the examples save in CS3 and F8 formats any help is appreciated greatly.

Regards,

Rich.

This is the ancient code, that has been passed for centuries, hidden from the outside world…


stopit.onPress = function() {
myTween.start();
myTween.stop();

};
