When I first started doing MS, I thought I wasn't getting the 2pt questions credits either because it doesn't credit right there in front of ya. Even if you hit the refresh button. It takes another point from click fix to "kick the question point in" or if you go to Milebuilder after doing 2pt question, you'll see it has credited. (This is REALLY hard to explain...the folks here who know what I'm talking about are probably cracking up at me trying to explain this.)
For example: I always do, trivia, lucky 7, then the 2pt question....After I do the 2pt question, the credit doesn't show up on the office page after I answer the question, but when I click on Milebuilder, to go do my click fix, I can see the points have appeared.....before Milebuilder, it would credit after along with my first click fix credit.
If you save the 2pt questions until the very last thing, you would think they aren't crediting at all, but would show up the next day when you log in...I think.
The moral of this story is, do the 2pt question before you click fix or Milebuilder and see if you don't see it show up that way.
Let me know if you're still having problems, but I think this will help you see that the 2pt question really do credit, they just need a little boost to show up!
Good Luck!
