Help please

I have figured out all of my other issues, but I can not get the damn
scrollbar to not be the annoying light grey color.

Here is what I am trying this is on frame 1


_global.style.TextArea.setStyle("scrollTrackColor", 0x4AD966);
parchment.backgroundColor = 0x151515;
parchment.borderStyle = "none";
parchment.html = true;
parchment.wordWrap = true;
parchment.multiline = true;
parchmentStyle = new TextField.StyleSheet();
parchmentStyle.load("parchment.css");
parchment.styleSheet = parchmentStyle;

parchmentContent = new XML();
parchmentContent.ignoreWhite = true;
parchmentContent.load("home.xml");
parchmentContent.onLoad = function(success)
{
if(success)
{
parchment.text = parchmentContent;
}
}

And FREAKING A THE DAMN THING wont change the scrolltrackcolor

What am I doing wrong? my eyes hurt from being retarded.
