In mod/quiz/report/overview/report.php on line 428 (v 1.27.2.13 2006/02/12 21:02:18) there is a typo

echo '<form id="attemptsform" method="post" action="report.php" onsubmit="var menu = document.getElementById(\'menuaction\'); return (menu.options[menu.selectedIndex].value == \'delete\' ? \''.$strreallydel.'\' : true);">';

should be something like

echo '<form id="attemptsform" method="post" action="report.php" onsubmit="var menu = document.getElementById(\'menuaction\'); return (menu.options[menu.selectedIndex].value == \'delete\' ? confirm(\''.$strreallydel.'\' ): true);">';

just for asking a confirmation on deleting

Bobo.
