Problem with C1_W2 assignement

I have passed all assignments but in the final submission process, I get zero points.
How can I solve this?

Perhaps you have changed something in the assignment (maybe the name or some cell). The best guess at this point is reset the assignment, you can save a copy of your work and copy paste it in the reset one.
