Provide Update

1. Progress
   I managed to make the changes requested of me by the issue and Wilny Duong.
2. Blockers
   I faced a pretty large blocker making this issue take about a week. This is a new issue copied from an old issue I had trouble with. For some reason, the branches I was creating become unable to be edited/closed/pushed to, which meant I couldn't update the pull request when needed. I troubleshooted, changed my origin and upstream, and left behind GitHub Desktop in favor of the command line and the Git wokrflow built into VSCode. However, I'm still unsure exactly what I'm doing so my second good issue will be a good way to test my knowledge. I also don't know to stage commits in VSCode yet, but I am learning.
3. Availability
   50 minutes, then Sunday I will be mostly available.
4. ETA
   Whenever the reviews come in! Maybe a few days?
