:-) Welcome @Shevans - this is the great thing about the weekly challenges, they're here when you are ready to get started (so no time is too late).
Nice work getting started - the weekly challenges were a huge learning journey for me, hopefully you get a lot out of them!
Just wanted to say Welcome, and congratulations on your first solution posted. I've personally found the weekly challenges to be one of the MOST valuable learning tools that I've come across for the alteryx product, and I hope that you'll find the same!
Good luck, and welcome to the journey. There's loads of fun ones ahead, so you've got a lot to look forward to.
