I am so sorry , I get an output like question this is question 41 << miss didnt get grade results
this is question 52 << works
you answered a when correct answer is c
it will not split the variable $questions_asked and and query the DB
correctly , maybe parsing the array is too fast for the query ???
I attached a results for a grading page
thanks
Jim
