I made no logic changes and submitted the answer again, and it seemed to work this time, so for whatever reason, I probably just fat-fingered the value, which I guess happens.

once you sit back and think about it, you come up with the REAL better way to approach it, iterative development is really interesting, but you have to understand your problem and have time to actually iterate on your solution to really be successful with it.
