    var m = 0;     var n = Qarray1[m];     $temp = "org_review[Q" + n + "]";     $res1 = document.getElementById($temp)      var flag = 0;

   for (var j = 1; j <= 20; j++)    {       $temp1 = "org_review[Q" + j + "]";       $res2 = document.getElementById($temp1)

            if ($res1 == $res2)      {                alert($temp);             flag = 1;      }      else      {         flag = 0;            }       }      if (flag == 1)      {              alert("Hey, please go throgh the questions... Its not boring");        return false;      }     }
