The issue is that you do not have any grading categories in your Gradebook Setup.

Steps to do this:

1. Click on Grade book Setup
   

2. Click on the Green Plus Sign to the right
   

3. Put a Category in and Save. If you want to more than one category (ie. Homework, Classwork, Quizzes, etc) you can add each one in. If you leave it as Unweighted you don't have to put in percentages, if you want it to be Fixed Weights you will need to have them add up to 100%.
