Reporting only answered questions to LMS

Hi

So here is a question that has got me stumped. (Phil you were recommended as the man that could solve it for me, but open to any suggestions from anyone out there)

We have a quizz that includes a "2nd try" question that is ony presented to the user if they fail the first try question. So we have a total of 10 questions, but if they user passes the "first try" question each time, they will only actually see 5 questions. (as the 2nd try question will be skipped using branching)

The problem is that the results will include all of these questions, even if the user didn't answer them, so the results will not be accurate.

To get around that we thought to use the variable %sum%points, which only sums up the actual scored questions.

The challenge now it to report the %sum%points to the LMS.

We tried using this method http://www.articulate.com/support/kb_article.php?product=st1&id=fdoq1b7qv49l which uses a Survey free text question to call a variable, and then submit it to the LMS. It works fine for sending a text entry, but cannot manage to send a sum variable. 

Worked with Dave Anderson on it and we concluded that we cannot get a text entry to populate with a sum variable.

So looking for another solution that can define if someone skips a question, don't record it as "failed" or "missed" but rather just ignore it, and then we can use the regular results slide.

Thanks!
