Trigger Error - Why does the 'SObject row was retrieved via SOQL without querying the requested field' error appear?

Hello, 
I am getting this error message in my Conference app when I try to assign a Speaker to a Session, I get this error message. Can you please explain why I am getting this error? I am also pasting the code for the Trigger. Thanks!

Please update your Query on line number 5 like below and add Session__r.First_Name__c in query.

Session_Speaker__c sessionSpeaker =
 [ Select Session__r.Name,
Session__r.Session_Date__c,
Session__r.Last_Name__c,
Session__r.First_Name__c,
Session__r.Email__c

The field in query is missing, add it as Amit chaudhary commented.

Thank you Amit and Mubeen! So as you explained the problem was that I was attemping to use a field in my confirmation email but that field was not part of my query.
