Actionscripting Problems with Full Screen Resize and Placement of borders

Alright, so I am having a problem getting my two borders to scale and stay placed at the very bottom and right below the logo I have placed in the upper right. The code is as follows…

stop();

Stage.scaleMode = “noScale”;

var HPositioner:Number = (Math.round((Stage.width - 917) / 2));
var VPositioner:Number = (Math.round((Stage.height - 700) / 2));

function HPositionCubes () {
if (Stage.width >= 917) {
var HPositioner:Number = (Math.round((Stage.width - 917) /2));
setProperty(topLeftCube_mc, _x, 0 - HPositioner);
setProperty(topRightCube_mc, _x, (917 + HPositioner) - 249);
setProperty(bottomLeftCube_mc, _x, 0 - HPositioner);
setProperty(bottomRightCube_mc, _x, (917 + HPositioner) - 89);
} else {
setProperty(topLeftCube_mc, _x, 0);
setProperty(topRightCube_mc, _x, 917 - 89);
setProperty(bottomLeftCube_mc, _x, 0);
setProperty(bottomRightCube_mc, _x, 917 - 89);
}
}

function VPositionCubes () {
if (Stage.height >= 701) {
var VPositioner:Number = (Math.round((Stage.height - 700) /2));
setProperty(topLeftCube_mc, _y, 0 - VPositioner);
setProperty(topRightCube_mc, _y, 0 - VPositioner);
setProperty(bottomLeftCube_mc, _y, (700 + VPositioner) - 84);
setProperty(bottomRightCube_mc, _y, (700 + VPositioner) - 84);
} else {
setProperty(topLeftCube_mc, _y, 0);
setProperty(topRightCube_mc, _y, 0);
setProperty(bottomLeftCube_mc, _y, 700 - 84);
setProperty(bottomRightCube_mc, _y, 700 - 84);
}
}

HPositionCubes();
VPositionCubes();

setProperty(topborder_mc, _width, Stage.width);
setProperty(bottomborder_mc, _width, Stage.width);  

var resizeListener:Object = new Object();
Stage.addListener(resizeListener);

resizeListener.onResize = function () {
setProperty(topborder_mc, _width, Stage.width);
setProperty(bottomborder_mc, _width, Stage.width);
HPositionCubes();
VPositionCubes();
}

The cubes are the 4 corners of the document… this I am not having a problem with, but the top border and bottom border I am having a problem with. I want the bottom border to stay at the very bottom of the full screen flash document no matter the size of the browser window. Basically I only want the border’s width to resize to the browser, not the height and also stay positioned at the very bottom. As for the top border I want it to be positioned under the topleftcube_mc. and stay positioned right under the logo at all times no matter how big or small the window. The top border’s width is the only thing I want to scale as well. Any help would be greatly appreciated. Thank you in advance.
