How to pass multiple field values to email template while using trigger directive?



I am not able pass multiple field values to trigger directive to trigger a template email. I have _fetch directive, followed by a _checkif interger comparison based condition and then if the criteria matches I have to trigger an alert.

Below is a structure of my query

  _fetch * from event where $Reason='<something>' AND $Message='<something>' AND $Duration=4h group count_unique  $User limit 1000
>>_checkif int_compare count_unique > 4 include
>>_trigger template_email <package> <template name> notify_group <notif group>

In the email alert I only receive the User name,however I need some more field values.
