Nested Switch/Case duplicate Default cases problem

*facepalm
That is why I put amateur right in the name!

Thanks everyone for taking a peak, and thanks killzone for seeing the typo problem.

I have a lot of stuff to learn about commands via the Serial Monitor and ASCII characters and what is going on with all that, but I'll keep grinding away at that issue myself for a while.
Thanks to TheMemberFormelyKnownAsAWOL I started trying out char variables for the Serial.read() so that's a whole new realm of stuff to mess with instead of checking ASCII values for everything.
