Please check Week 3 and Week 4 Grader

Hi,
There seems to be problems with the grader. It says the following when X is defined by the scaffolding code itself:
There was a problem compiling the code from your notebook. Details:
name ‘x’ is not defined

Showing similar compiling error in week 4 as well.

Hi @SidBan ,

Try refreshing the kernel and rerun the code from start.

Week 3 1st exercise worked after deleting the files and then refreshing. Thank you.

Using # grade-up-to-here also helped.
