The problem is located in the line bellow: > $result9 = mysql_query("SELECT * FROM kommentar WHERE (id=$myrow8["id"]) ", $db); The select statement was closed when you write the second " so you have to change it to: $result9 = mysql_query("SELECT * FROM kommentar WHERE (id=" . $myrow8["id"] . ") ", $db); You may also ad slashes to it but some times it becomes a unreadable code, I'd rather this way. I hope this helps.

I want to use it in a second search in another table, "kommentar", wich also has a tinyint row called "id".
