got this code - to control one scroller bar behind a mask

stop();
this.onEnterFrame = function() {
this.webThumbs._x = (-650/800 * _root._xmouse);
}

----

works fine - however i have another scroller on the page using the same code obv with a differnt instant name. looks like this.

----

stop();
this.onEnterFrame = function() {
this.webThumbs._x = (-650/800 * _root._xmouse);
}


this.onEnterFrame = function() {
this.printThumbs._x = (-650/800 * _root._xmouse);
}

i am a novice so please be nice if my mistake is an obvious one..
when publishing only one scroller works? anyone shine any light on this please will be mighty usful. thanks you
