Question : How do I get information from a function outside the function

In a showtip function I have some text, which has a textHeight, that I need outside the function to create a drawrectangle.
But how do I get the number outside the function to use in the drawrectangle.
The text varies in length and is based on xml

square_mc.onRollOver = function() {
                showTip(someXmlText);
}

function showTip(str) {
      container.toolTip.tipText.text = str;
      autoHeight = container.toolTip.tipText.textHeight;     //This is the number I need in the drawRoundedRectangle below
      container.toolTip._visible = true;
      container.toolTip._x = _root._xmouse;
      container.toolTip._y = _root._ymouse;
               onMouseMove = function () {
            container.toolTip._x = _root._xmouse;
            container.toolTip._y = _root._ymouse;
        updateAfterEvent();
    }
}

drawRoundedRectangle(container.toolTip, ttWidth, autoHeight, 16, 0x99FF00, 100);
