Unchecked checkboxes are not posted. I prefer to use a the null coalescing operator (??) when handling checkboxes EG $Bold = $_POST['Bold'] ?? 0; //if not set, default to '0'2 points

the attached code doesn't produce a php syntax error. there are only 270 lines. any chance you made a change and didn't save the file before trying to execute it? btw - addslashes() should never have been used with database code.1 point

I had to create my own test data (thanks for that) but naturally I don't know how it conforms with yours. TABLE: product TABLE: bookingItem +----+-------------+-----------+--------+ +----+-----------+---------------------+---------------------+----------+ | id | productName | category | status | | id | productid | startTime | endTime | quantity | +----+-------------+-----------+--------+ +----+-----------+---------------------+---------------------+----------+ | 1 | Room 1 | Guestroom | Active | | 1 | 1 | 2024-01-01 11:32:01 | 2024-01-02 11:32:59 | 1 | | 2 | Room 2 | Guestroom | Active | | 2 | 2 | 2024-02-01 11:34:08 | 2024-02-03 11:34:24 | 2 | | 3 | Room 3 | Guestroom | Active | | 3 | 3 | 2024-03-01 11:34:56 | 2024-03-04 11:35:08 | 3 | | 4 | Room 4 | Guestroom | NULL | | 4 | 2 | 2024-04-01 12:20:20 | 2024-04-07 12:20:41 | 6 | | 5 | Room 5 | Guestroom | NULL | | 5 | 3 | 2024-05-01 01:21:49 | 2024-05-05 12:21:58 | 4 | +----+-------------+-----------+--------+ | 6 | 5 | 2024-06-19 12:23:03 | 2024-06-29 12:23:28 | 10 | | 7 | 2 | 2024-06-01 13:02:51 | 2024-06-15 13:03:16 | 14 | +----+-----------+---------------------+---------------------+----------+ On running your code with my data I get these results for Q1 and Q2. I have written the correct totals in red. As you can see there is a distinct pattern - your totals are the correct totals squared. However, I could not spot any multiplication in the code (I ran as separate query to confirm the correct totals) I have to say, in your code you really make a meal of those dates in the years and quarters considering that SQL can handle it easily. Here's my version... <?php ############################################### # CREATE YOUR OWN PDO DATABASE CONNECTION # # # require 'db_inc.php'; $pdo = mdbConnect('db1'); # # # # ############################################### $range = [ '2020-01-01', '2024-07-31' ]; $selectedYear = $_GET['year'] ?? 0; $whereYear = ''; if ($selectedYear) { $whereYear = 'AND YEAR(d.dt) = ?'; $range[] = $selectedYear; } $res = $pdo->prepare("WITH RECURSIVE dates(dt) AS ( SELECT ? UNION ALL SELECT dt + INTERVAL 1 MONTH FROM dates WHERE dt < ? ) SELECT YEAR(d.dt) AS yr , QUARTER(d.dt) as qtr , MONTHNAME(dt) AS mth , productName AS room , COALESCE(SUM(DATEDIFF(endTime, startTime)), '-') AS nights FROM product p CROSS JOIN dates d LEFT JOIN bookingitem b ON b.productid = p.id AND YEAR(d.dt) = YEAR(b.startTime) AND MONTH(d.dt) = MONTH(b.startTime) WHERE p.`status` = 'Active' $whereYear GROUP BY yr, qtr, MONTH(d.dt), p.id "); $res->execute($range); $results = $res->fetchAll(); $rooms = array_unique(array_column($results, 'room')); $theads = "<tr><th>Quarter</th><th>Month</th><th>" . join('</th><th>', $rooms) .
