Moodle in English

Dear all, thanks for helping out in advance!

I'm helping with a project. This site has a customization (for Moodle 1.9) called braindband custom completion. However, this whole 3rd party module is kind of buggy, and I'm trying to trouble shoot a weird problem. It is running on top of a LAPP stack. It added four custom tables and injected some codes into some of the core library files (bad practice, I know):

• mdl_completion
• mdl_completion_instances
• mdl_ges_grade_categories
• mdl_ges_grade_category_progress

            if ($tmp AND $tmp->timeinstructor > 0)
                print_heading(get_string('completed','completion'));
            else {
                $tmp = get_record_sql("
                    SELECT gcp.user_id, gcp.graded, gc.applicable_items
                    FROM {$CFG->prefix}ges_grade_category_progress gcp
                    JOIN {$CFG->prefix}ges_grade_categories gc ON (gc.grade_item_id = gcp.grade_item_id)
                    JOIN {$CFG->prefix}grade_items gi ON (gi.id = gc.grade_item_id)
                    WHERE gi.courseid = {$course->id} AND gi.itemtype = 'course'
                        AND gcp.user_id = {$user->id}
                ");
                $mh_format_progress = format_float($tmp->graded * 100.0 / $tmp->applicable_items, 1);
                print_heading('Progress: '. ($tmp ? ($mh_format_progress > 100) ? '100' : $mh_format_progress : '0.0') .' %');
