Get 0/100 in lab even I get all test passed

I followed the instruction to update the lab for many times, even I get all test passed for every questions, I still get 0 after grading. I am sure that I save my answer, and my answer only change the “None” part…
It says There was a problem compiling the code from your notebook. Details:‘NoneType’ object is not subscriptable.
I don’t know how to fix it, really need some help, Thanks!

Dear @Dongli_Li,

Please send me your notebook through email(because code share in the community is against the rule)

I’ll look into your code and let you know the problem.

Thanks

This means there is some other problem in your notebook, which is confusing the grader.

For example, did you use the “# grade up to here” comment tag?
Have you completed all of the parts of the assignment?
Are you using the current version of the notebook?

@Girijesh Hello,

Where could I find your email? Thanks!

@TMosh Hello Tom,
I didn’t use grades up to here and completed all parts. And I think I am using the current version.
