How to solve "Error: A test did not resolve to TRUE or FALSE"?

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

I haven't programmed on the Nspire before, but when I have logic errors like yours, I strip out everything but the tests themselves, and then make a truth table of all possible inputs, so I can manually feed the logic statements their inputs. Also can you find out at what line the program stopped working via the Goto option or by inserting Disp commands?
