        for (PracticeBean practiceBean1 : listPractice1) {
            int pr_id1 = practiceBean1.getPr_id();
            String pr_name1 = practiceBean1.getPracticeName();
    %> 


            var cookiename=getCookie(<%=pr_id1%>);

            if (cookiename!=null && cookiename!="")
            {

                x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
                y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
                x=x.replace(/^\s+|\s+$/g,"");
                if (x==c_name)
