puoi provare così:

codice:
<script type="text/javascript"> 
     
    function init_dw_Scroll() { 
        var wndo = new dw_scrollObj('scroll', 'txt'); 
        wndo.setUpScrollControls('arrows'); 
    } 


    function init_dw_Scroll2() { 
        var wndo = new dw_scrollObj('scroll2', 'txt'); 
        wndo.setUpScrollControls('arrows2'); 
    } 


    if ( dw_scrollObj.isSupported() ) { 
        dw_Event.add( window, 'load', init_dw_Scroll);
        dw_Event.add( window, 'load', init_dw_Scroll2);
    } 
     
    </script>
