I figured out how to fix two issues I was having with the code thanks to the help of posters above-- namely this kind soul's explanation of how to make the header change from purple to blue. I also implemented at this person's suggestion, but changed the font from 9pt to 10pt-- that made it fit perfectly.

Thus, the only issue I have left is a weird blue line that runs along the leftmost edge of the comments (screenshot). If you could help me figure out how to fix that, I think the code is more or less perfect!

Thank you so much for your help so far, and I know it must be overwhelming to wake up to all this. ♥
