How do I fix Illegal Name Value Exception?

[ssell714]

I am a teacher and have two students that got this error for their final projects. I noticed someone else ran into this and someone (Dr. Kidnapper, I believe) was able to fix these errors by unzipping the file and changing some code on the backend.

Would someone be able to fix the code below (my other student's code is 40 MB, too big for uploading here)? If you would also be willing to share with me how to fix this in the future, that would be awesome! Thank you so much. This forum has been really helpful so far - thanks for everyone's posts!
