By no means am I a coder/developer but I was excited to have made it this far. I am literally having trouble with this last step and I am not sure how I am to format my code. The goal is to:

1. Make the class global, implement the Batchable interface, and define the three methods of the interface​
2. Declare three instance variables to store the query, the email subject, and the email body
3. Define a constructor implemented
4. Implement the start() method 
5. Implement the execute() 

I am not sure if these tasks were to be executed seperately or combined within the code all together. Here is where I'm at:





Any help is greatly appreciated!
