I have completed Lab 2a. Every time I press refresh to score it, I get a 0. I also get an error message that says invalid date when running the code, but it says success eventually. I have tried running the code a few times in Chrome and Edge. I have also tried clearing the cache.
Hello,
I have completed the steps.
