Newbie scrollpane help!

I create a super simple .fla using flash MX 2004 professional

I put this code under the button I created

on (release) {
var mc = _root.createEmptyMovieClip(“trianglemajor”, 1);
mc.createEmptyMovieClip( “triangle”, 5000);
with (mc.triangle) {
lineStyle (5, 0xff00ff, 100);
beginFill(0xff00ff, 100);
moveTo (150, 25);
lineTo (200, 25);
lineTo (200, 75);
lineTo (150, 75);
lineTo (150, 25);
endFill();
}

var panex = 10;
var paney = 290;
_root.attachMovie(“FScrollPaneSymbol”, “mcScrollPane”, 250, {_x: panex, _y: paney});
mcScrollPane.setVScroll(true);
mcScrollPane.setScrollContent(mc);
mcScrollPane.setSize(100, 100);

}

I just see a blank screen when I click on the button

what I’m doing wrong

My objective is to show the movieclip mc inside my created scroll pane ?

any help will be greatly appreciated.
