Course 5, Week 3, Assignment 2, Submission error

The Second lab in week 3 has any submit button. I reset the assignment, but it didn’t fix.
What am I supposed to do?

Hi ,

Here is a couple of things to check:

  1. security setting on your device
  2. browser setting - change to a different browser to see if it helps.

It could be a problem at Coursera, if so contact the Learner Help centre.

Also try restarting the kernel.

That’s worked. Tank you.
