I'm trying to use the ArrayFormula of Google Sheets to set an auto-fill system where the contents of one column update as I add more data to another column, but, with the formula I'm using, the first set of cells will just use the first value in the second set, making every cell have the same content(which is the opposite of what I want). Here's an [idea](https://docs.google.com/spreadsheets/d/10lzcVnuLiEEaoyqmo2p-L7ykvZrfHXrQs0ZhrH2V7N0/edit?usp=sharing) of what I'm trying to do.
