[PHP] Help with msql_fetch_array()

[Matthew Bielecki]

I have a couple of scripts that fail with the error of:
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result 
resource in...

I'm new to both SQL and PHP and I'm wondering if I have some setting 
turned off or what.

Here's the piece of code that is failing (the second line fails):

$result = mysql_db_query($dbname, "SELECT * FROM tablename ORDER BY id");
        $row = mysql_fetch_array($result);


Thanks for your help in advance!!
