Excellent
Thank You
Your github is not updated since past one year Nate?
Trying out the StrataScratch question – I'm returning two records, Mia and Farida, both with 400 for the total and their respective order dates, but it's not accepting it. The Expected Output button is showing 430 for the order totals, but I'm not seeing that order total in the data. Am I missing something?
Edit: Ah, multiple orders on the same date, got it. Was thrown off since you had 400 in your video there.
What do you think about using the RANK function to handle the case of ties?
Great video.
Awesome video as always!
