You have already been told by Disco Octopus what the problem is, (did you
even read his reply?).
Look at the code bellow and it will show you where the error is.

if ($row2['ra_id_given_id']!=0)
{
$q3=mysql_query("SELECT * FROM quiz_report_questions WHERE
rq_id=$row2[ra_id_given_id]", $link);
$row3=mysql_fetch_array($q3);
if ($row2['correct_ra_id']!=0)
{
$q4=mysql_query("SELECT * FROM quiz_report_answers WHERE
ra_id=$row2[correct_ra_id]", $link);
$row4=mysql_fetch_array($q4);
if ($row4['answer_tag']==$row3['answer_tag'])
{
$ncorrect++;
}
else
{
$nwrong++;
}
}
else
{ //bad test
$bad=true;
}
////////////////////////////////////////////////////
// this else has no if!!!!
////////////////////////////////////////////////////
}
else
{ // user gave no answer. doesn't matter if no answer available.
if ($row2['correct_ra_id']!=0)
{
//answer available. consider it wrong. don't even have to look
it up.
$nwrong++;
}
}
}

And in my experience, "(?!?interpreter bug?)" usually means that you are
wrong.
