Above mentioned is my fetchXML i would like to read the apitil_title and apitil_description values.

I tried the following methods but could not get the value :

{% assign app_cust = approval_action_query.results.entities %}

{% for approver in app_cust %}  

{{entities.apitil_servicerequest[approver.apitil_description]}}{{entities.apitil_servicerequest[approver.apitil_description].name}} {{entities.apitil_servicerequest[approver.apitil_description].value}} {{entities.apitil_servicerequest[approver.apitil_description].id}}

{% endfor %}
