Tell us what’s happening:
My code fails the first 4 and last 2 tests. It is weird because when I check them, they work fine. I have tried looking in the developer console but I have hit a wall. At this point I have spent a little less than half the time I spent on coding to debug this and I have absolutely given up. If anyone can nudge me in the right direction, I would really appreciate it. Apologies for having such a clunky and often redundant code. I am not sure where the formatting error is especially since I have personally check amount of spaces and other items. Again, I am not sure what the error is just that it makes my code fail the first 4 and last 2 tests.
Your code so far
