{
    if(!globalDiv)
    {
        if(!document.getElementById(divID))
        {
            var newNode = document.createElement("div");
            newNode.setAttribute("id", divID);
            document.body.appendChild(newNode);
        }
        globalDiv = document.getElementById(divID);
        var x = queryField.offsetLeft;
        var y = queryField.offsetTop + queryField.offsetHeight;
        var parent = queryField;
        while(parent.offsetParent)
        {
            parent = parent.offsetParent;
            x += parent.offsetLeft;
            y += parent.offsetTop;
        }
        if(!divFormatted)
        {
            globalDiv.style.backgroundColor = DIV_BG_COLOR;
            globalDiv.style.fontFamily = DIV_FONT;
            globalDiv.style.padding = DIV_PADDING;
            globalDiv.style.border = DIV_BORDER;
            globalDiv.style.width = "100px";
            globalDiv.style.fontSize = "90%";           
            globalDiv.style.position = "absolute";
            globalDiv.style.left = x + "px";
            globalDiv.style.top = y + "px";
            globalDiv.style.visibility = "hidden";
            globalDiv.style.zIndex = 10000;
            divFormatted = true;
   
        }
