Hi @ajb176! Great job with this pull request! The branches are set up correctly and there is a correctly formatted linked issue. You made only the requested change to the code and no visual changes resulted on the website, as expected. Keep up the good work!

I can see the change to double quotes, the branch name is descriptive, and branch itself is set up as it should be. Only thing is the formatting of the bullets in the issue is missing a space, so the dashes are appearing as themselves instead of bullets.

This is what you have:
" -some text"

vs. what it should be between the quotes to get the bullet points for next time:
" - some text"

Otherwise, great job @ajb176 !
