   var update_Account = new sforce.SObject("Account")
   update_Account.Id = accountId;
   update_Account.Rating= 'HOT';
   updateAccountRecords.push(update_Account );
   sforce.connection.update(updateAccountRecords);
   alert('Account Rating is converted to HOT');
   window.location.reload();
} else if(accountRating == 'HOT'){
   alert('Already HOT');
}
else {
