How to scroll a MC using buttons in MX2004

Hi all,

I'm having a great deal of difficulty doing something that I found pretty easy in old versions of Flash - maybe I'm just too tired!

How do you scroll a movie (up and down) in MX 2004 using both up and down buttons?

Can anyone provide a link to or fla example?

Many thanks!

put the whole movie clip on the stage. Put 2 buttons on the side. Put a mask over the area you want to see. Then do something like this for the movie clip that's going to scroll:

onClipEvent (enterFrame) {
if (_root.rollup == true) {
if (this._y>=topboundary) {
this._x -= 15;
}
}
if (_root.rolldown == false) {
if (this._y<=bottomboundary) {
this._x += 15;
}
}
}

where _root.rollup is changed by...

on(press){
_root.rollup==true;
}


on(release){
_root.rollup==false;
}

get the idea?
