$sessionid = $logquery->fetchrow_array;
$sessionid = '0' if not defined $sessionid;
$sessionid++;

This works great until $sessionid = 10, then $sessionid++; does not increment to 11. Later in the code I insert $sessionid into a database and after 10 I get a PK violation. How do I make $sessionid increment larger than 10.
