The 7.10 reading starts with "Activity: CodeLens 7.10.1 (strParsing)". This exercise (strParsing) has a problem. The displayed code refers to a variable called spacepos, however all answers get marked as incorrect. The reason is that the .rst code for the exercise is checking the variable globals.sppos (not spacepos), and the exercise instructions also refer to sppos rather than spacepos. I'm not sure whether the correct name is spacepos or sppos, but presumably the name should be consistent throughout the exercise.
