           var s = document.getElementById("statusZY"+i).value;
           var casesInfoId = document.getElementById("casesInfoIdzy"+i).value;

           var statejbt = document.getElementById("statezyt"+i).value;
           var statejbo1 = document.getElementById("statezyo"+i);
           var statejbt1 = document.getElementById("statezyt"+i);
           if(s==20){
              stringC+=s+"@"+casesInfoId+","; 
           }
           if(s==1){
              if(statejbo1.checked){
