I did my lab 2b and my screenshots match the screenshots for both the checkpoints. But when I tried grading it I received a grade of zero for both the checkpoints and the grader did not even provide me with feedback on what I did wrong. I tried redoing my work and deleted the list of meetings. Now that I am redoing my work, step 17 doesnt match for me as I am getting a different number for both mapped and unmapped fields. I have also attached screenshots from my initial attempt. Please help me as my assignment is due very soon.
