Looping through sets in order

[Kurt Kaufman]

Perhaps I misunderstand, but:
If you can set a "flag" variable such as "SFQuiz1Passed", can't you also 
set additional flags afterwards, such as "SFQuiz2Passed", etc., or even 
"SFQuiz1.1Passed" if you need the user to advance to multiple question 
sets on each "level"?
Can we assume that the user cannot advance to SFQuiz2 until SFQuiz 1 is 
complete?  If that's the case, then you'd only have to check which 
SFQuizXPassed is contained in the "X" part of the variable to continue 
to the next set.....

HTH, Kurt
