I'm also working through this course myself now, and I believe code more along the lines syntactically of how "Current Period?" is defined, but in reference to the initial period of of the Model calendar with inequality instead of equality of the logical test is a more robust solution than making reference to the current period. Ideally Anaplan would provide a kind of time indexing function, analogous to the WEEK and DAY functions, that can work relative to the Model Calendar or a user-specified time range, and thus allow for the creation of solution more easily generalized than mine, but if it exists, it's not easily found in the officially documentation.
