Having issues to understand how to do the 3rd level of the hierarchy

I'm currently working on the Capstone activity for Smartsheet, and one of the activities is:

Organize your sheet by establishing three levels of hierarchy.

1. The highest level of hierarchy should be the month

2. The middle level of hierarchy should be the individual weeks (weeks 1-4)

3. The lowest level of hierarchy should be the requests within a given week

I have done the first 2 of these but not sure what I have to do for the 3rd one, could someone explain it ? Thanks
