    In the following javascript, the scrollX and scrollY are always zeros althought I clicked a radio button at the bottom of the form. I found on the internet that one person changed HTML 4.0 to 3.2 in <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> and took care of the problem. I tried but still got zeros. Any idea? Thanks.

    function SmartScroller_GetCoords()
    {
    var scrollX, scrollY;

    if (document.all)
    {
    if (!document.documentElement.scrollLeft)
    {
    scrollX = document.body.scrollLeft;
    }
    else
    {
    scrollX = document.documentElement.scrollLeft;
    }

    if (!document.documentElement.scrollTop)
    {
    scrollY = document.body.scrollTop;
    }
    else
    {
    scrollY = document.documentElement.scrollTop;
    }
    }
    else
    {
    scrollX = window.pageXOffset;
    scrollY = window.pageYOffset;
    }

    document.Form1.scrollLeft.value = scrollX;
    document.Form1.scrollTop.value = scrollY;
    confirm(scrollX);
    confirm(scrollY);
    }
