Hena, April is right - don't worry about getting those numbers to match the instructions for 2a.
But do note - in 2b there are some references to Meeting ID numbers that will be different in your account because of the different Meeting ID numbers that you've got in there now. Don't worry, it will all still work but the Meeting ID numbers will be 3 higher than what is shown in Lab 2b. So then is stays "Mtg-008" in lab 2b, it will be Mtg-011 in your account. But it should be fine that way.
