Error Message Sequences, Time Series and Prediction C4W1 'name 'series_valid' is not defined

I am working on C4W1 Sequences, Time Series, and Prediction for the lab. I have passed all the tests, but I still received a score of 0. There was an issue compiling the code from my notebook. Please check that I saved before submitting. The error message says: 'name ‘series_valid’ is not defined
