Courses Plus Student 36,045 PointsWhy doesn't this work? top_referrals_index = users.where(users['referral_count'] > 4 & users['email_verified'] == True)
Optional Challenge 1, I feel like I've tried everything but it keeps failing the tests. Can anyone see why the email_verified check is returning some False values?

Treehouse TeacherIt looks like you're missing some parentheses (). You want to surround your expressions with parentheses to control the order of operations. The example given at the bottom of this instruction step is a good reference. I also removed the 'where' using the example as my guide. See if this works for you.
top_referrals_index = users[(users['referral_count'] >= 5) & (users['email_verified'] == True)]

Courses Plus Student 36,045 PointsOK, I cleared the kernel, ran everything again, in order, and I copy/pasted your code. It still fails. Stumped.

Treehouse TeacherNo worries! We'll figure this out :)
Here's how I am inputting the above statement into the binder. Are you doing it the same way?

Courses Plus Student 36,045 PointsOK, so apparently Jupyter was angry that I made a new cell and ran it...that was the actual problem
Thank you so much. I really do appreciate your patience.

Courses Plus Student 36,045 PointsThis looks good, and it looks like one of the versions I tried by consulting various pandas resources on the inter-webs. It still fails all the tests based on not having only TRUEs and having some returns with less than 5 referral counts. However, when I view the whole data frame for top_referrals_index, the output is correct (so, the answer should work, and probably so should some of mine.)
Is it possible there is something wrong with the testing program? Thanks for responding. I hope we can figure this out. I know it's optional because I'd like to pass it.

Treehouse TeacherHey, Nancy!
I tried the above in the binder notebook and it passes all tests for me. I left it as:
users[(users['referral_count'] >= 5) & (users['email_verified'] == True)]
I tried at first the recommended Kernel > Restart and Run All but that didn't change the table view at all so instead I ran each cell individually and that changed the table view and showed that I passed all tests. Try running each cell from the top-down individually and see how that goes.
