What am I doing wrong? [beginner]

AHHHHHRGGG this is getting me on my nerves!!!##!! I am using a mySQL-databasetable called controllpoints_tbl with the following structure: +----+------------+-----------+-----+------+-----+-------------------------- ---------------------------+ | nr | process_nr | type | abb | name | x | description | +----+------------+-----------+-----+------+-----+-------------------------- ---------------------------+ | 1 | 1 | Milestone | MS | MS1 | 200 | bla bla bla | | 2 | 1 | Milestone | MS | MS2 | 500 | bla bla bla | | 3 | 1 | Tollgate | TG | TG1 | 100 | bla bla bla | | 4 | 1 | Milestone | MS | MS4 | 600 | bla bla bla | +----+------------+-----------+-----+------+-----+-------------------------- ---------------------------+ I want to view just the "name" and "x" variable with this code... for ($i=1;$i<=$antal_typer;$i++) { $typvar = $type[$i]; // this is an array with types $here = 150+17*$i; echo "Hello"; $result = mysql_query("select name,x FROM controllpoints_tbl where process_nr=$process_nr and type=$typvar order by x"); while ($myrow = mysql_fetch_row($result)) // this is line 138... { // here's a lot of code.. } } but it never enters the while loop.. and only print Hello one time although $antal_typer = 2; a warning message says: Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in c:\inetpub\wwwroot\devproc\beta\view.php on line 138
