Summit's Gate - Part 1 - odd error in Python [Solved]

Working on the first part of Summit’s Gate. Getting a very odd error: “Assigning to rvalue” and it isn’t giving me a line number or any other reasonable way to track it down. Anyone able to spot where I messed up?

Thank you very much … was looking right through those. :frowning:
