Ultimate Web Site Drop Down Menu Forum - Don't understand what's needed to get popup relative to link to work

You'll notice in the code below that I am pointing back to this website for css and js. Can someone please give me a sample of what should go in each of these? I have a working version of UDM4 working on my website. But now I am trying to create a second menu and understand that popup is my only choice here. Also can someone clarify -- can I have one drop down and then mulitiple popup menus or do I have to reconfigure my drop down nav bar as popup menus when I add a second nav bar?

Code:

    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

        //open menu with given ID 

        function openMenu(menuID,linkObj)

        {

            //if the menu code is ready

            if(um.ready)

            {

                //find co-ordinates of link object

                var coords = {

                    'x' : um.getRealPosition(linkObj,'x'),

                    'y' : um.getRealPosition(linkObj,'y')

                    };

                    

                //increase y-position to place it below the link

                coords.y += (linkObj.offsetHeight + 4);

                

                //activate menu at returned co-ordinates

                um.activateMenu(menuID, coords.x + 'px', coords.y + 'px');

            }

        }

        

        //close menu with given ID

        function closeMenu(menuID)

        {

            //if the menu code is ready

            if(um.ready)

            {

                //deactive menu

                um.deactivateMenu(menuID);

            }
