I tried using formula tool, to define Jan to Dec, then realized strings are repeating, and also thought of inserting another text input, but wanted to practice multi row formula usage. Good exercise:)
I poked around a few of the solutions after I had finished mine. I knew there had to be a way to parse out alpha and numeric characters to separate the month and year. I found it but since I didn't know how to do it before, I kept this solution.
