I am attempting to complete the assignment for this week, but I am having a problem with the first exercise. I am receiving the following output/error.

AssertionError: Not all tests were passed for get_sub_volume. Check your equations and avoid using global variables inside the function.

I am unsure why this error is occurring. I see nothing in my code that is incorrect.

Hi @cdwetal,

Can you please share with me in a private message your code so that I can check it?

@grizbi is your issue address or you still need help. Also avoid commenting on too old threads. Always create a new topic so you don’t miss this topics you encountered in your learning journey. Please create a new topic, you can always tag a link comment post which you find similar to your issue but sharing your own error screenshot, rather copy paste error is better choice at understanding any error to debug. You can even tag any mentor you want them to have a look using @
