As some of you may recall, I recently noticed an error where parameters being sent to GetComponent() (and similar calls) were not showing up. I believe this is being caused by formatting being performed by WordPress that results in the parameters being stripped out because they are in angle brackets. I apologize for any difficulties this has caused people as they have been attempting to follow along. I have now gone back and fixed all (or at the very least the majority) of these occurrences in the first 15 parts of the tutorial. Hopefully this means that no more people have this problem in the future.
Note: For anyone wanting to post comments including these parameters, simply add some whitespace either side of the parameter, as that seems to fix the problem.
