Multiple Choice Question Issues

Question

I am embedding a quiz within my presentation with individual
question slides interspersed throughout the presentation. These
questions are pulled from a couple of different question pools. I
want to use a multiple choice question that branches to different
parts of the presentation depending on the correct or incorrect
answer. If the user answers the question incorrectly, I send them
to the next slide which has two click boxes. On this slide, they
can either click one box to move back in the presentation and
review the material or click another box to move them forward to
another multiple choice question. If they go back and review the
information, they would eventually return to the same multiple
choice question to try it again. (This is the desired navigation,
anyway.)
What actually happens is that when the user goes back to
review the information and then finally returns to the question,
the question has not been reset and still shows the incorrect
answer marked with no way to clear it.
I have used this same navigation on a drag-and-drop type
question and it works fine. All the settings for the
multiple-choice questions are set the same as in the drag-and-drop
question.
Any help in making this work correctly would be greatly
appreciated.

I can't see where that error might arise except possibly for a case where an AS2 radio is used since it appears they don't have a group property, but an AS3 radio button does.  Check to be sure that your Flash Publish Settings are set to use AS3.  AS3 errors normally have error numbers which also makes the error you quoted ring of an AS2 scenario.
Here's a link to the file I made based on your code that works fine and doesn't display the errors you mention.  It is a CS3 file.
