Individual points for multiple response questions

Hi, this question is for Dave.

I have been working on this same problem, I thought that I was getting it to work, but found that the hidden slides are adding additional points to the total possible points that the quiz uses for grading.  I may have missed a step?  My quiz had 26 possible points, but after adding a hidden true & false question and a 3 point multiple choice (similar to your example) the total possible is now 30.  Is there a way for the quiz results not to include the value of the hidden slides when figuring to the score?

Thanks for your assistance!!
