$row10 is undefined here, so:
$row10 = mysqli_fetch_row($result10); ?
I would suggest using
while (($row1 = mysqli_fetch_row($result1))!= 0 ) { ... }
instead of
do { ... } while (($row1 = mysqli_fetch_row($result1))!= 0 );
This avoids the need of the extra mysqli_fetch_row before the do-while loop.
