Fixed bug #994, so we have in chart like the below:
1) student1 111115212121 12/12 122221172111 12/12
2) student2 11111*191221 12/12 211*112 3.21 10/12
....
99) student99 1223224*7232 12/12 3145.1245*** 11/12
100) student100 121123244241 12/12 213.132216*4 11/12
but still the following code in lonstudentassessment does not work!
my $out = '';
$out .= sprintf("%3d) ", $Count);
if($Count % 2) {
$out .= '<bgcolor="#FFFFFF">';
} else {
$out .= '<bgcolor="#505050">';
}
